"Latar Belakang: Kemampuan mastikasi merupakan kemampuan untuk memecah partikel makanan agar mudah dicerna tubuh sehingga berperan dalam pemenuhan nutrisi. Penggunaan gigi tiruan lepasan diperlukan ketika seseorang mengalami kehilangan gigi karena dapat mengurangi kemampuan mastikasi. Berbagai faktor lain juga dapat mempengaruhi kemampuan mastikasi. Tujuan: Menganalisis hubungan berbagai faktor terhadap kemampuan mastikasi pemakai gigi tiruan lepasan. Metode: Tiga puluh empat pemakai gigi tiruan lepasan (GTL, GTLT, dan GTSL) berpartisipasi dalam uji mastikasi dengan permen karet yang dapat berubah warna (Masticatory Performance Evaluating Gum Xylitol®) dengan desain potong lintang. Laju alir saliva dievaluasi dengan gelas ukur, dan ketinggian residual ridge diukur secara klinis menggunakan kaca mulut No.3 yang diberi ukuran mm. Hasil: Ketinggian residual ridge (p=0,003) dan pengalaman memakai gigi tiruan (p=0,051) berperan terhadap kemampuan mastikasi. Faktor usia (p=1,000), jenis kelamin (p=0,711), laju alir saliva (p=0,400), jenis gigi tiruan (p=0,218), dan jumlah serta lokasi kehilangan gigi (p=0,097) tidak memberikan hubungan yang bermakna.

Background: Masticatory performance is the ability to breakdown food to facilitate digestion, and its role in nutrition is important. Removable dentures are used to rehabilitate loss of teeth, which could jeopardize masticatory performance. There are also various factors that affect masticatory performance.

Objective: To analyze the relationship between various factors and masticatory performance.

Method: Thirty four removable denture wearers (full dentures, single complete dentures, or partial dentures) participated in a cross-sectional study of masticatory performance using color-changeable chewing gum (Masticatory Performance Evaluating Gum Xylitol®). The volume of saliva were evaluated using measuring cups, and residual ridge heights were measured using modified mouth mirror no. 3 with metric measurements.

Result: Residual ridge height (p=0,003) and removable denture-wearing experience (p=0,051) had significant relationship with masticatory performance. Age (p=1,000), gender (p=0,711), saliva (p=0,400), denture types (p=0,218), the number and the location of missing teeth (p=0,097) did not have significant association with masticatory performance.

"ABSTRAKLatar belakang : Keberhasilan gigi tiruan dukungan implan sangat ditentukan oleh stabilitas awal (primary stability) pada saat pemasangan, sehingga terjadiosseointegrasi. Stabilitas tersebut dipengaruhi oleh beban oklusal yang diterima melalui restorasi sementara. Beban oklusal yang diterima implant pada , dapat secara langsung pada saat implantasi (immediateloading) atau setelah terjadi osseointegrasi (delayed loading). Masih banyak kontroversi mengenai pengaruh besar beban pada stabilitas implan. Oleh karena itu, perlu dilakukan penelitian seberapa besar pengaruh kontak oklusal pada restorasi terhadap stabilitas implan yang dipasang secara immediate loading.Metode : Pada tiga ekor Macacafascicularis, dilakukan pemasangan Sembilan implant gigi. Segera setelah implant ditanam pada tulang, restorasi sementara dipasang pada implant dengan kontak ingan, normal dan tanpa kontak. Nilai stabilitas implant diukur menggunakan Ostell ISQ segera setelah pemasangan implan, bulan pertama dankedua setelah pemasangan implan.Hasil : Terdapat perbedaan bermakna dari nilaistabilitas implan (p<0,05) antara kelompok kontak oklusal normal dengan tanpakontak; dan kontak oklusal normal dengan kontak ringan. Namun tidak ditemukan perbedaan bermakna (p>0,05)pada kenaikan nilai stabilitas implan yang terjadi antara periode baseline, bulan pertama dan bulan kedua pada seluruh kelompok kontak oklusal.Simpulan: Terdapat pengaruh kontak oklusal restorasi sementara pada implan yang dipasang secara immediateloading terhadap stabilitas implan dan kontak oklusal yang menghasilkan nilai stabilitas paling besar setelah pemasangan implan adalah restorasi tanpa kontak.

ABSTRACT

Introduction: successful of dental implant were determined by primary stability when placement. The stability were influnced by occlusal loading thriugh provisional restoration. There are two types of loading protocol that usually used, immediate and delayed loading. But there are still controversies about the influence of occlusal loading on implant's stability. Therefore, it was necessary to study the influence of immediate loading to implant's stability.

Method: Nine dental implants were placed on the mandibular of three Macacafascicularis. Provisional restorations with various occlusal contacts (no contact, light, and normal contact) were placed to the implant. Implant stability was measured using the Ostell ISQ three times, immediately (baseline), first month and second month after implant placement.

Result: Implant stability between implant with no occlusal contact and normal contact and also light occlusal and normal occlusal contact were found significantly different (p<0,05). However, there was no significant increased (p>0,05) found on implant stability measured at baseline, first and second month after implant placement for all occlusal contact groups.

Conclusion: There were influence of immediate loading to implant's stability and provisional restoration of implant without occlusal contact showed highest implant good stability result."

Background: Loss of teeth can reduce the ability of the body such as during mastication, speech, aesthetics, and disorders of the joints. One solution to replace missing teeth is to use removable dentures. There are several factors that influence the success of treatment, including knowledge and confidence possessed by the operator. Confidence can support the implementation of the procedure correctly. Knowledge is gained during the learning process. A positive perception of the learning process can increase student enthusiasm and confidence. Objective: To determine the frequency distribution of clinical year students' confidence in handling removable denture treatment, and the stage prosthodontic treatments, also to determine their perception of the quality of prosthodontic studies. Method: An observational descriptive study with a cross-sectional design. Retrieval of data using a questionnaire distributed online to all clinical year students and will be filled by clinical year students who have done 1 case of complete denture and at least 1 case of partial denture. Furthermore students are grouped according to the year of entering the professional program. Data were analyzed with descriptive test to find out the mean value. Results: There were 80 clinical year students who met the inclusion criteria and were willing to fill in the questionnaire. The highest confidence levels of clinical year student in performing removable prosthodontic treatment are found in the 2013 group when performing partial denture treatment (8,00) and try-in stage of partial denture (wax) (9,00) and also the 2014 group taking primary impression for complete denture (9,00). More than 95% of the FKG UI clinical year students who filled out the questionnaire had a positive perspective on the prosthodontic learning they received. Conclusion: The confidence of clinical year students is higher in handling removable partial denture treatment and in specific treatment is higher when taking primary impession and try-in stage (wax). The majority of professional students have positive perceptions of prosthodontic learning at FKG UI."

"Perawatan gigi tiruan pada lansia terutama lansia perempuan usia 50-75 tahun sering mengalami kegagalan, karena adanya resorpsi tulang alveolar berlebihan yang menyebabkan gigi tiruan longgar dan tidak stabil. Berbagai penelitian penyebab terjadinya resorpsi tulang telah banyak dipublikasi, di antaranya yang terkait faktor sosiodemografis, klinis, dan lingkungan, namun penelitian terkait dengan hormon (PTH, FSH) dan faktor genetik (polimorfisme gen PTH dan PTHR1) belum banyak diteliti.Tujuan: Memperoleh indeks tingkat keparahan resorpsi tulang alveolar mandibula untuk memprakirakan tingkat keparahan resorpsi tulang alveolar mandibula pada pascamenopause yang memerlukan perawatan gigi tiruan. Subjek penelitian adalah perempuan pascamenopause usia 50-75 tahun yang bertempat tinggal di kelurahan Kenari dan Paseban Jakarta Pusat.Metode: Menggunakan alat ukur kuesioner indeks kepadatan tulang mandibula tervalidasi, pemeriksaan klinis, pemeriksaan serum darah dengan ELISA, dan teknik PCR RFLP untuk menganalisis gen, dan evaluasi radiograf panoramik untuk menilai kualitas tulang kortikal mandibular. Selanjutnya dilakukan penelitian potong lintang untuk mencari faktor-faktor risiko yang paling berperan terhadap keparahan resorpsi tulang alveolar mandibula.Hasil: Penelitian ini menunjukkan tidak terdapat hubungan antara faktor sosiodemografis, klinis, dan lingkungan, serta ditemukan sebanyak 87,25% subjek dengan kadar PTH <65pg/mL, dan adanya korelasi yang signifikan antara kadar PTH dengan resorpsi tulang alveolar mandibula (p<0,05). Kadar PTH ≥65pg/ml bertendensi terhadap tingkat keparahan resorpsi tulang alveolar. Tidak ditemukan adanya korelasi antara kadar PTH dengan genotip dan alel polimorfisme gen PTH pada posisi rs6254 di intron dua (p>0,05). Tidak terbukti adanya korelasi antara polimorfisme gen PTH dengan keparahan resorpsi tulang alveolar mandibula (p>0,05), sedangkan pada polimorfisme gen PTHR1 pada posisi promoter tiga ditemukan bahwa pada pengulangan (AAAG)6 memiliki kualitas tulang yang lebih rendah dan resorpsi tulang tinggi walaupun tidak ditemukan adanya korelasi antara polimorfisme gen PTHR1 dengan keparahan resorpsi tulang (p>0,05). Hasil uji multivariat memperlihatkan kadar FSH, PTH dan kualitas tulang alveolar mandibula berperan terhadap terjadinya keparahan resorpsi tulang alveolar mandibula (p<0,05). Penelitian ini memperoleh dua model penskoran indeks prediksi keparahan resorpsi tulang alveolar mandibula. Model satu dengan faktor PTH, FSH dan kualitas tulang mandibula mempunyai sensitifitas 68,29%, spesifisitas 56,48%, dengan daerah di bawah kurva (AUC) 0,675 dapat digunakan jika pada penerapan model dua tidak terlihat faktor yang berperan. Model dua terdiri dari FSH dan kualitas tulang, dengan sensitivitas 68,29% dan spesifisitas 58,33% serta area daerah di bawah kurva (AUC) 0,649.Kesimpulan: indeks prediksi resorpsi tulang alveolar mandibula yang terdiri atas analisis kualitas tulang mandibula, kadar FSH dan PTH dapat digunakan untuk memprediksi tingkat keparahan resorpsi tulang alveolar mandibula. Dengan demikian diharapkan kegagalan perawatan gigi tiruan pada perempuan kelompok usia 50-75 tahun yang berisiko osteoporosis dapat diatasi.

Denture treatment in the elderly, especially in women aged 50-75 years, often experience failure, due to excessive alveolar bone resorption which causes loose and unstable dentures. Various studies have been published on the causes of bone resorption, including those related to sociodemographic, clinical, and environmental factors, but research related to hormones (PTH, FSH) as well as genetic factors (PTH and PTHR1 gene polymorphisms) have not been much studied.Purpose: This study aims to obtain a mandibular alveolar bone resorption severity index to predict the severity of mandibular alveolar bone resorption in the postmenopausal period that requires denture treatment. The subjects of the study were postmenopausal women aged 50-75 years who lived in the villages of Kenari and Paseban, Central Jakarta.Methods: The first step this study were conducted by using a validated mandibular bone density index questionnaire, clinical examination, blood serum examination by ELISA, and PCR- RFLP techniques to analyze genes, and panoramic radiographs evaluation to assess the quality of mandibular cortical bone. A cross-sectional study to look for the risk factors that most contribute to the severity of mandibular bone resorption were then conducted at the second step of this study.Results: This study showed no relationship between sociodemographic, clinical, and environmental factors, and found as many as 87.25% of subjects with PTH levels <65pg / ml, as well as a significant correlation between PTH levels with resorption of the mandibular alveolar bone (p <0.05 ). The PTH level ≥65pg / ml has a tendency towards the severity of alveolar bone resorption, however, there was no correlation between PTH levels with genotype and PTH gene polymorphism alleles at position rs6254 in intron two (p> 0.05). There is no proven correlation between PTH gene polymorphism with the severity of mandibular alveolar bone resorption (p> 0.05). In the PTHR1 gene polymorphism of the promoter position three it was found that the repetition (AAAG)6 had lower bone quality and higher bone resorption although no correlation was found between PTHR1 gene polymorphisms and the severity of bone resorption (p> 0.05). Multivariate analysis showed that the levels of FSH, PTH and mandibular alveolar bone quality were contributed to the severity of mandibular alveolar bone resorption (p <0.05). From this study two predictive index scoring models of the severity of mandibular alveolar bone resorption were obtained. The model one with factors of PTH, FSH and quality of mandibular bone, has 68.29%sensitivity and 56.48% specificity, with the area under the curve (AUC) 0.675. Model two has a sensitivity of 68.29%, and specificity of 58.33% with the area under the curve (AUC) is 0.649. The model one could be used if in the application of model two does not show factors that play a role.Conclusion: the predictive index of mandibular alveolar bone resorption consisting of analysis of mandibular bone quality, FSH and PTH levels can be used to predict the severity of mandibular bone resorption. It is hoped that the failure of denture treatment in women aged 50-75 years at risk of osteoporosis can be overcome."

Background: Accuracy of the impression is important in making dentures, especially in implant-supported complete dentures. This systematic review conducted to compare accuracy of digital impressions using intra-oral scanners and conventional impressions.

Method: This systematic review followed the Preferred Reporting Items for Systematic Review and Meta Analysis (PRISMA) and registered on PROSPERO with number CRD42023478021. Four databases and a manual search system limited to publication date 2008-2023 period. Literature evaluated based on data discusses accuracy of digital and conventional implant-supported denture impressions carried out in cases with minimum four implant on fully edentulous jaw. Risk of bias assessment was performed using the Cochrane RoB-2 and ROBINS-I.

Result: A total of 368 literature was obtained from four databases and 297 literature was selected based on title and abstract after duplicate removal. A total of seven literature from the database met the inclusion criteria and was combined with one literature resulting from a manual search. Eight literature were analyzed. Three- dimensional accuracy of impressions varies but is still within the clinically acceptable range (200μm). Dentures from all impressions also has a good passive fit. Radiographically, the majority of dentures produced do not have voids between the superstructure and the implant. Quality assessment with Grading of Recommendation Assessment Development and Evaluation (GRADE) shows high level of quality evidence for all literature.

Conclusion: Based on the results of this analysis, conventional and digital impressions results have comparable accuracy in clinical applications."

"The overall objective of this study is to evaluate the long term results of interpositional connective tissue graft and horizontal and vertical bone augmentation in recessed area of interproximal papilla.Atrophic ridges rebuilt through GBR procedures. For this study, 2 major alterations are made in the surgical technique describes. First, the horizontal and vertical bone augmentation graft is obtained from autograft like ascending ramus or allograft with or without platelet-rich plasma and barrier membrane. Second, connective tissue for interpositional grafting is obtained from hard palate. This interpositioning graft would be success by use of pouch technique or envelope flap technique. From 1998, among over than 120 patients of implant treated for this study, regardless of 1-staged or 2-staged surgery or type of implant surface treated, 60 implants of 18 patients which has a dissatisfaction on anterior region, food impaction on posterior region subjectively or has a black-triangle on anterior and flattened inter-implant spaces clinically was selected. Differences of success rate between inter-dental and inter-implants depend on blood supply and distance between implants. Autografts, PRP and anorganic bovine bone Bio-Oss have been successfully employed for isolated augmentation area. It is essential to make the CT graft neovascularize to a recipient site, overcorrection of graft, immobilization of graft and tension-free suture. based on annual measurements of gross texture, pocket probing depth, attachment level, and width of keratinized mucosa, this 5-year study indicates that interpositional CT graft when used in conjunction with appropriate bone augmentation technique, can become successfully esthetics and yield predictable maintenance results."

"Proper and clear pronunciation are problems that usually rising in patients with edentulous ridge. To overcome that problem a full denture is highly needed, so that the patients can eat well, to fulfill the esthetic problems and good in speaking. In Phonetics there is a difference between vocal and consonant, it depends on how the modification of the air flow in respiration in the oral cavity. In this research, the point of view is the linguopalatal consonant /c/ and /j/ that had a place of articulation in front of the palatum. In full denture wearers there is a difficulty in pronouncing this consonant properly because the Upper Full Denture has a palatal plate, in which this linguopalatal consonant has a place of articulation in the middle of the palatum. This research evaluated the quality of pronouncing the linguopalatal consonant after the day of insertion, after 3 days, 10 days and also before using denture. 25 respondents using denture for the first time and 3 researchers evaluated the proper and clear pronunciation of 6 words (cacah, cicih, cucu, jajah, jijik, juju). The results of this study is there is no progress in proper pronunciation using word cacah, cicih and cucu. On the other hand there is an increase about 20% in good pronouncing the word jajah, and also there is a decreasing percentage in pronouncing word jijik and juju. After day 10, all of the words can be pronounced well except word jijik. So there is a special characteristic in full denture wearers for consonant /c/ and /j/"
