A dogmatic view on occlusion as the main aetiological factor for temporomandibular disorder (TMD) has been present in the literature for a long time, but a direct scientific correlation between occlusal disorders and TMD has never been proven. The purpose of this study was to determine the frequency of TMD signs and tissue-specific diagnoses in a population of 164 asymptomatic participants, 70 removable partial denture wearers and 94 complete denture wearers of an average age of 61.3 years, by means of clinical manual functional analysis. TMD was found in 42.1% of the participants. No statistically significant difference in the occurrence of TMD was found between removable partial and complete denture wearers and between genders (P > 0.05). The most frequent tissue-specific diagnoses were osteoarthrosis (11%), total anterior disc displacement (9.1%) and partial anterolateral disc displacement (8.5%). The frequency of tissue-specific diagnoses was also not influenced by the type of prosthetic replacements.

Objectives: To assess the concepts of complete denture occlusion among dental fraternity. Study Design And Setting: Cross-sectional study conducted at various dental hospitals and institutes of Karachi, for a period of six months, from 1st June’2019 to 30th November’2019 Methodology: Total 849 dental practitioners who are currently practising were included. A well-structured and validated questionnaire was used for data collection. SPSS version 25 was used. Results: Bilateral balanced occlusion was an ideal occlusion by majority subjects i.e, 530(62.4%) in patients with wellformed ridges, followed by 464(54.7%) candidates with skeletal class 1, total 376(44.3%) chose it with uncontrolled diabetes mellitus, 365(43%) in single complete denture cases, 339(39.9%) with increased inter-arch space, 298(35.1%) with parafunction habits, 296(34.9%) in patients with history of neuromuscular disorder and 271(31.9%) where a complete denture opposes a removable partial denture. Furthermore, Lingualized occlusion was preferred by 341(40.25%) participants for patients with skeletal class 3. Total 316(37.2%) candidates chose it for patients with displaceable supporting tissue followed by 264(31.1%) who chose it for skeletal 2 and 260(30.6%) for cases of highly resorbed ridges. Lastly, 311(36.6%) chose canine guided occlusion with highly resorbed ridges accompanied by high aesthetic demand A significant difference between education level and knowledge of occlusal schemes was also found. Chi-square (73.87), df 6, p-value =0.000. Conclusion: Dental practitioners lack adequate knowledge of occlusal schemes in terms of prescription in complete denture patients. A significant difference between the education level and knowledge of occlusal schemes was found. Therefore, awareness of various occlusal schemes should be increased at undergraduate level.

Objective: To evaluate and compare the effect of implant supported versus implant retained removable partial denture restoring Kennedy's class I cases on the supporting structures by measuring modified gingival index and probing depth for abutment teeth and implants. Subjects and Methods: Twelve patients; who had Kennedy class I mandibular partially edentulous ridge extending distal to the first or second premolar,   were selected from the outpatient clinic, Prosthodontics Department, Faculty of Dentistry, Minia University. The patients were classified into two equal groups; according to the implant superstructures either dome shaped abutment or ball and socket attachment.  Each Patient of both groups had two implants in second molar position (one in each side) and received removable partial denture of the same design. Patients were followed up for one year clinically. Group I: Six patients received RPD supported by dome shaped short abutments.  Group II six patients received RPD retained by ball and socket attachments. Results: Results revealed that, there was no statistically significant difference between the two groups regarding modified gingival index and probing depth around the abutment teeth and implant abutment. Conclusion:  The use of dome shaped abutment or ball and O-ring attachment have the same effect on gingival index and probing depth around natural abutments and implants in Kennedy class I mandibular situations.

Edentulous Patients

Removable partial denture are prosthetic solutions that replace missing teeth of partially edentulous patients, ensuring stomatognathic system functionality with affordable costs.The purpose of this study is to analyze the dimensional variations caused by the execution errors, which can lead to premature deterioration of the removable partial dentures and to conclude what sizes are deficient and can lead to the deterioration of the prosthetic part. The material involved in the present study was represented by the metal framework of 181 removable partial dentures. Of the total of 181 removable prosthetic parts, 88 were maxillary prostheses and 93 were mandibular prostheses. Measurements were made at the retentive arms, opposing arms, minor connectors, rests and junction areas between the body of the clasps and the active arms and studied compared to the edentulous classes. The results are focused on dimensional changes of both the retentive arms and the opposing arms of the clasps, which are roughly modeled in the first 3 edentulous classes, with a significant difference from those achieved in Kennedy`s 4th class edentulous, where these segments of the clasps are much shorter. Regarding the size of the rests, although their thickness approximates the values indicated in the literature, they do not fit into the occlusal relief of the tooth. The length of the retentive arms varies according to the classes of edentulous, the clinical situation, but also the size and type of the tooth (premolars, molars) on which the clasp is applied. Regarding the opposing arm, the observed differences cannot be correlated with the objective criteria of their achievement because the attention is directed towards the realization of the retentive arm.

Background Among many options to replace missing teeth, dental implant is widely popular but willingness to have implant treatment and its success depends on patients’ knowledge and expectations as well as the care, skill, and judgment of clinicians. Objective The main objective of this study was to assess awareness, expectation and source of information about dental implant among complete and removable partial denture wearers and to find association between them. Method A questionnaire consisting of 6 close-ended questions was used to assess the level of knowledge and awareness among patients visiting Dental Outpatient Department of Dhulikhel Hospital regarding dental implants as a treatment option for replacing missing teeth. Chi-square test was used to study the association between demographic variables and awareness about implantation. Statistical software SPSS 20.0 was used for data analysis. Result Our results revealed significant difference in age (p=0.001), education level (p=0.03) and occupation (p=0.004) in awareness of dental implant and no significant difference in gender (p=0.567), compared between complete and removable partial denture wearers. Due to lack of awareness, lower educational status and advanced age the patients responded that they “did not know “ in answer to almost all the questions. Conclusion The awareness level of dental implant was low among complete and removable denture patients and this was associated with a low level of education and lack of accurate information about dental implants.

BACKGROUND: Patient’s satisfaction and the preservation of abutments is the most important outcomes that the clinician seeks during fabrication of any dental treatment, especially when it is concerned with removable prosthodontic rehabilitation. AIM: The present study evaluates three different Removable Partial Denture (RPD) types restoring mandibular class II modification I edentulous cases with regards to patient’s satisfaction and abutments survival. METHODS: Forty-two partially edentulous patients were divided into three groups (Group I rehabilitated with Vitallium RPD, Group II rehabilitated with Vitallium RPD where the modification area restored with the surveyed bridge, Group III rehabilitated with Thermopress RPD). The patients were followed up for twenty-four months. Using a questionnaire, prosthodontic maintenance required was documented at the delivery and after 3 months. RESULTS: There was a significant difference regarding patient satisfaction for group III (P-value <0.05) while for groups I and II there was a non-significant difference (P-value >0.05). Regarding the survival rate, there was a non-significant difference between the three groups (P-value >0.05) at the end of twenty-four months of follow up. CONCLUSION: Patient satisfaction and abutment survival were better with Thermopress RPD than conventional Vitallium RPD or Vitallium RPD with a surveyed bridge restoring the modification area. Although a non-statistically significant difference was found in the survival rate of abutments between groups, a clinically important result was revealed as no abutments failures were reported in the Thermopress group.

Latar belakang. Bahan yang dipakai untuk pembuatan Gigi Tiruan Sebagian (GTS), antara lain: resin akrilik, kerangka logam, kombinasi kerangka logam dengan resin akrilik. Resin akrilik adalah bahan plat gigi tiruan yang memliki warna dan translusensi baik tetapi sifat mekanismenya tidak ideal, tidak tahan terhadap abrasi, dan dapat terjadi perubahan dimensi. GTS kerangka logam cukup kuat, tetapi estetis kurang memuaskan sehingga perlu kombinasi kerangka logam dan resin akrilik. Peningkatan daya lekat antara kedua bahan tersebut memerlukan retensi, teknik etsa kimia dengan akua regia dapat membuat retensi mikro pada logam. Tujuan penelitian untuk mengetahui etsa kimia dengan akua regia terhadap kekuatan tarik perlekatan bahan resin akrilik pada gigi tiruan kerangka logam. Metode penelitian. Penelitian dilakukan pada 20 subyek penelitian berupa plat kobalt kromium dengan mesh dilekati resin akrilik (10x10x2) mm yeng dilekati mesh ukuran (10x8x1) mm. Subyek penelitian dibagi 2 kelompok: 10 subyek plat kobalt kromium dengan mesh dilekati resin akrilik (20x10x2) mm dan 10 subyek penelitian plat kobalt kromium dengan mesh dietsa dengan akua regia 65% selama 5 menit, kemudian dilekati dengan resin akrilik (20x10x2) mm. dilakukan uji kekuatan tarik menggunakan Torsee’s universal testing Machine dengan ukuran kg/mm2, kemudian hasil analisa dengan t-test. Hasil Penelitian menunjukkan rata-rata kekuatan tarik perlekatan bahan resin akrilik dengan kerangka logam yang tidak dietsa lebih kecil daripada yang dietsa kimia dengan akua regia. Terdapat perbedaan yang bermakna kekuatan tarik perlekatan resin akrilik dengan kerangka logam yang tidak dietsa dengan yang dietsa secara kimia dengan akua regia (p<0,05). Kesimpulan. Etsa kimia dengan akua regia pada kerangka logam, meningkatan perlekatan bahan resin akrilik pada gigi tiruan kerangka logam. Background. Materials used in making removable partial denture (RPD) can be acrylic resins, metal plate, combination between metal plate and acrylic resins. Acrylic resins is plate denture material have good colour and translucent but the mechanical characteristic is not ideal, unstable to the abrasion, and can be occurred change in dimension. The frame removable partial denture is strong enough but estethically unsatisfaying, therefore need the acrylic resins and metal plate combination RPD. The purpose of this study was to know the influence of chemical etching with akua regia towardbond strength of acrylic resins in frame denture. Methods. The study was conducted in 20 subject of chromium cobalt plate (10x10x2) mm that was attached with a mesh measurement (10x8x1) mm. The sample were devided into two groups. The first group consisted of 10 samples of chromium cobalt plate (10x8x2) mm with a mesh was attached with acrylic resins (20x10x2) mm. The second group consisted of 10 samples of chromium cobalt plate (10x10x2) mm with a mesh etched with 65% akua regia for 5 minutes, than attached with acrylic resins (20x10x2) mm. the bond strength test was carried out using Torsee’s Universal Testing Machine in kg/mm2, than was statistically analyzed using t-test. The result of this study demonstrated that mean of bond strength of acrylic resins combined with nonetched metal plate was smaller than that with etched metal plate. There was a significant difference of the bond strength of acrylic resins combined with metal plate etched and that with metal plate non-etched (p<0,05). Conclusion. The chemical with akua regia in the metal frame increases the attachment of the acrylic resin in the frame denture.
