Abstract

Loss of teeth in adult needs to be replaced with dentures to restore masticatory and esthetic functions. Dentures are made immediately before extraction and used immediately after extraction, so that they do not change in appearance or function. If patient has restorable teeth, the teeth can be used as denture support. Overdentures supported by one or more restored teeth or implants as periodontal and mucosal support to improve durability of the denture. This arti-cle discusss maxillary immediate denture and mandibular overdenture on a woman who felt uncomfortable with the denture that has been used for 4 years. Patient wants a new denture without changing appearance. Intraoral exa-mination found tooth 17, 16, 26 GIC fillings, 13 dowel crown, 31, 32 PFM crowns, 42 composite filling with mobili-ty grade I, and 44 caries. This case was managed with extraction teeth 16, RCT 26, and extraction 13 before insert-ion the maxillary immediate denture with cusil #17 and overdenture 26, and also RCT was performed on 44, 42, 32, 31 followed by insertion the magnetic overdenture 44, 42 and metal coping overdenture 31, 32. It is concluded that immediate denture and overdenture provide optimal results for esthetic improvement and patient satisfaction.

Abstract

The extraction of impacted third molars is one of the most common treatments performed in oral and maxillofacial surgery. Most third-molar surgeries are performed without complications, although still can cause serious complications in patients, one of are temporomandibular joint disorders (TMD). This study aims to determine the effect of third molar extraction on TMD that con-ducted using preferred reporting items for systematic reviews and meta-analyses (PRISMA) protocol through the databases PubMed, Ebsco, Sage, Scopus, and Springer with relevant keywords and published 2012-2022. The articles were then selected and evaluated eligibility. Detailed data extracted by google spreadsheet. Six articles were included in this rapid review, consisted of retrospective study (n=1), prospective cohort study (n=1) retrospective cohort study (n=1), review (n=2), and syste-matic review (n=1). It is concluded that there was an effect but not significant between extraction of impacted third molars and TMD related to various influencing factors. These factors include the complexity of the procedure, age, and gender. There is no definitive relationship due to the variation in the sample and research methods, and no quality assessment was conducted.

Abstract

Introduction: Treating malpositioned anterior teeth requires more than just prosthodontic intervention. A collaboration with orthodontic treatment is the preferred approach for patients with compromised cases. Due to their predictable results and tooth structure conservation, lithium disilicate veneers are indicated for the aesthetic rehabilitation of anterior teeth with malpositioning or anomalous appearance. This case report discusses the aesthetic rehabilitation of upper anterior teeth that were compromised by missing teeth and post orthodontic treatment, using lithium disilicate veneers. Case Report: A 25-year-old female patient came to the Department of Prosthodontics at Universitas Padjadjaran Dental Hospital seeking to improve her smile. The treatment history revealed that the patient had just finished her orthodontic treatment. Clinical examinations showed the absence of upper left central incisor, causing the lateral incisor to occupy the central incisor position, the canine to occupy the lateral incisor position, and the premolar to occupy the canine position. Lithium disilicate veneers were proposed and the patient consented to the treatment. A dental impression was taken, followed by a diagnostic wax-up, mock up and finally, lithium disilicate porcelain veneers were placed. Lithium disilicate was chosen due to its high aesthetic properties and minimally invasive preparation. Conclusion: Aesthetic rehabilitation of upper anterior teeth that were compromised by missing teeth and post orthodontic treatment with lithium disilicate veneers is highly technique- and material-sensitive. However, when used with proper knowledge and skill, these restorations provide excellent aesthetic and functional outcome.

Abstract

Introduction: The loss of anterior teeth can lead to aesthetic, phonetic, and functional issues. A lithium disilicate adhesive bridge can be a good alternative and a viable compromise in cases of anterior tooth loss. The advantages include minimally invasive preparation, adhesive system, better retention, and aesthetics compared to metal materials. Removable orthodontic treatment is a preliminary option for cases of minor tooth malposition to achieve an ideal dental arch. This case report describes the management sequence for a missing incisor with tooth malposition using removable orthodontic appliances and modified design adhesive bridge. Case report: A 19-year-old female patient visited Dental Hospital Universitas Padjadjaran, Bandung with an issue of missing left central incisor due to traffic accident, and the right central incisor being in a crossbite position. The patient wanted to use a fixed dental prosthesis to improve her appearance but had not yet undergone correction for the misaligned tooth. Discussion: The patient was provided with a temporary removable dental prosthesis with removable orthodontic modifications including the addition of bite risers. Subsequently, a modified design adhesive bridge with lithium disilicate material was planned. Conclusion: The combination of removable orthodontic treatment with a final restoration utilizing a modified design adhesive bridge using lithium disilicate material for the upper anterior teeth can enhance patient satisfaction by addressing aesthetic concerns and improving phonetic function and chewing ability.

Abstract

Introduction: The improvement of ceramic has increased due to highly demand for aesthetic restoration. Ceramic at its nature is a brittle material that highly susceptible to be cracked, that leads to chipping and fracture of the restoration. Composite resin frequently used as a replacement for ceramic repair as a simple and fast solution. The success relies on the bond strength between ceramic and composite. The purpose of this study was to evaluate the shear bond strength of two ceramic repair system to low-glass ceramic lithium disilicate. Methods: This study was experimental laboratory, ten specimens of lithium disilicate ceramic was fabricated. Specimen was divided into two groups, first group include: grinding and treated with ceramic primer and second group: acid etching with hydrofluoric acid and treated with silane. Each specimen was subjected to a shear load at the parallel speed of 0,5mm/minutes until fracture using universal testing machine. Results: The shear bond strength achieved in group two (acid etching and silane) was higher than the group one (grinding and ceramic primer). The t-test one tailed analysis yielded p value 0,0057. The different was significant (p value < 0,05). Conclusion: In this study it is concluded that when treated with acid etching hydrofluoric acid and silane, lithium disilicate yielded higher bond strength with resin composite than when treated with grinding and ceramic primer.

Abstract

ABSTRACTIntroduction: Indirect restorations, such as fixed porcelain-fused-to-metal (PFM) crown and bridge prostheses, require tooth preparation that follows established principles to achieve restoration success. One of the preparation principles that needs to be considered is the taper angle, resulting from the axial wall tapering. To achieve maximum retention, the recommended taper angle is 6°. In clinical practice, preparation errors are frequently found, such as over-reduction and difficulties in axial tooth reduction. Thus, clinical education is required to improve students’ competence and skills to achieve recommended and more precise preparation results. The aim of this study was to evaluate the taper angle of porcelain-fused-to-metal (PFM) crown preparations performed by dental students. Methods: The study was conducted using a descriptive observational design with a total sample of 30 patients at the Prosthodontics Department at RSGM Unpad treated by clinical students of FKG Unpad. The patients’ jaws were scanned using a digital intraoral scanner, then the size of the taper angles were measured using CorelDRAW, with the ideal taper angle of 6-10°. The collected data were analyzed statistically using the chi-square test. Results: The average taper angle formed mesiodistally and buccolingually was 25,0° ± 14,5° and 14,9° ± 12,7° respectively, both of which were greater than the recommended taper angle. Conclusion: The preparation of porcelain-fused-to-metal performed by FKG Unpad clinical students did not reach the ideal taper angle. Dental students should receive hands-on clinical training to evaluate their tooth preparation performance and outcomes, in order to achieve high quality dental care for patients, using either conventional methods (extracted teeth) or digital methods (dental simulators, augmented reality).KEYWORDS: porcelain-fused-to-metal crown restoration, taper angle, tooth preparationPenilaian sudut taper pada preparasi mahkota porcelain-fused-to-metal yang dilakukan oleh mahasiswa kedokteran gigi: Studi observasionalABSTRAKPendahuluan: Restorasi tidak langsung, seperti mahkota dan jembatan tetap porcelain-fused-to-metal (PFM), memerlukan preparasi yang harus mengikuti prinsip preparasi gigi yang telah ditetapkan untuk mencapai keberhasilan restorasi. Salah satu prinsip preparasi yang perlu diperhatikan adalah sudut taper yang dihasilkan dari kemiringan dinding aksial. Untuk mencapai retensi maksimal, sudut taper yang direkomendasikan adalah 6°. Dalam praktik klinis, kesalahan preparasi masih sering ditemukan, misalnya reduksi berlebih (over-reduction) dan kesulitan dalam melakukan reduksi aksial gigi. Oleh karena itu, pendidikan pada tingkat klinis diperlukan untuk melatih kompetensi mahasiswa serta meningkatkan keterampilan mereka agar dapat mencapai hasil preparasi yang sesuai rekomendasi dan lebih presisi. Tujuan penelitian ini untuk menilai sudut taper pada preparasi mahkota porcelain-fused-to-metal (PFM) oleh mahasiswa kedokteran gigi.  Metode: Penelitian ini dilakukan menggunakan studi observasional deskriptif dengan jumlah sampel 30 pasien di Departemen Prostodonsia Rumah Sakit Gigi dan Mulut Universitas Padjadjaran yang dirawat oleh mahasiswa klinik Fakultas Kedokteran Gigi Universitas Padjadjaran. Rahang pasien dipindai menggunakan pemindai intraoral digital, kemudian besar sudut taper diukur menggunakan CorelDRAW, dengan sudut taper ideal 6–10°. Data yang diperoleh dianalisis secara statistik menggunakan uji chi-square. Hasil: Rerata sudut taper yang terbentuk secara mesiodistal dan bukolingual berturut-turut adalah 25,0° ± 14,5° dan 14,9° ± 12,7°, yang lebih besar daripada nilai sudut taper yang direkomendasikan. Simpulan: Preparasi porcelain-fused-to-metal yang dilakukan oleh mahasiswa klinik tidak mencapai nilai sudut taper ideal. Mahasiswa kedokteran gigi direkomendasikan untuk dilatih melalui pengalaman klinis langsung guna mengevaluasi performa dan hasil preparasi gigi mereka, sehingga dapat mencapai kualitas perawatan gigi yang tinggi bagi pasien, baik dengan metode konvensional (gigi asli pasca-ekstraksi) maupun metode digital (simulator kedokteran gigi, augmented reality).KATA KUNCI: restorasi mahkota porcelain-fused-to-metal, sudut taper, preparasi gigi.

Abstract

Introduction: Replacement of a single missing posterior tooth can be effectively achieved using a fixed dental prosthesis (FDP). Resin-bonded FDPs provide a conservative alternative to conventional full-coverage FDPs because they require minimal tooth reduction and preserve the remaining tooth structure while maintaining function and aesthetics. However, short clinical crowns and lingually inclined mandibular molars may compromise retention, resistance, and the path of insertion. This case report describes the use of a modified porcelain-fused-to-metal (PFM) resin-bonded FDP with onlay metal wings and adhesive bonding to manage a mandibular molar with a short clinical crown and a lingually inclined abutment. Case report: A 25-year-old male patient was referred to the Prosthodontics Clinic for replacement of a missing mandibular right first molar. The tooth had been extracted approximately one year previously. Intraoral examination showed that tooth 47 was lingually inclined and had a short clinical crown. Panoramic radiography showed adequate bone support and no pathological findings, indicating that the abutment teeth were suitable for prosthetic treatment. The treatment plan involved a modified PFM adhesive bridge with a sanitary pontic replacing tooth 46 and onlay metal wings on teeth 45 and 47. Retention was achieved through a combination of mechanical interlocking, chemical bonding, and adhesive cementation. At the one-week follow-up after FDP insertion, the prosthesis demonstrated satisfactory fit and occlusion, and the patient reported no discomfort or functional problems. Conclusion: A modified onlay-wing design for a lingually inclined abutment with a short clinical crown, combined with adhesive resin cementation to a metal framework, may provide a simplified and predictable approach for replacing a mandibular molar using a resin-bonded FDP.
