Purpose: This review was intended to discuss the various possible modifications suggested in the literature for prosthetic steps and surgical corrective procedures in nonresponding or complicated cases during rehabilitation of patients with restricted mouth opening.

Material And Methods:: Medline, PubMed, and Google were searched electronically for articles using keywords: microstomia and treatment options for restricted mouth opening. The various articles on prosthodontic rehabilitation in microstomia were segregated.

Purpose: The purpose of the study was to evaluate by a 3-dimensional finite element analysis the load transmission to periimplant bone by a framework supported by 6 implants placed in an edentulous mandible and to compare the stress distribution for varying cantilever lengths.

Methodology: A computerized model of the anterior segment of a mandible with a 6-implant-supported bridge was created in software. The length of the cantilever segment was considered as 10, 15, and 20 mm.

Purpose: This study evaluated the microbial colonization of dental implants in healthy patients before placing the implants and during the various stages of implant treatment.

Materials And Methods: Saliva (in completely edentulous patients) and gingival crevicular fluid samples (in partially edentulous patients) were collected from patients and analyzed to estimate the growth of microorganisms after culture. Samples were collected during 10 phases of implant placement and prosthesis insertion.

Article Synopsis
  • This meta-analysis compares conventional implant designs to "platform-switched" implants, focusing on their impact on crestal bone loss.
  • A thorough literature review analyzed various studies, finding that platform-switched implants led to significantly less marginal bone loss than platform-matched implants.
  • The study concludes that platform switching may help maintain bone and tissue levels around implants, but more long-term studies are needed to fully understand its effectiveness and optimal design.

Statement Of Problem: Although criteria for assessing bone quality have been reported, an overall score that correlates bone quality with the primary stability and secondary stability of implants is not yet available.

Purpose: The purpose of this article was to propose a scoring index that will establish a correlation among the bone density values from computed tomography, maximum insertion torque values, and resonance frequency analysis in different phases of implant treatment.

Material And Methods: In this study, 60 implant sites were evaluated to assess bone density (Hounsfield units), insertion torque values (Ncm), and primary stability and secondary stability (implant stability quotient values obtained by using resonance frequency analysis).

This article describes a technique for repair of abutment tooth which fractured during removal of a provisional restoration before bisque trial. The technique uses plastic templates to fabricate new composite core foundation for the existing crowns. This technique helps the dentist to rebuild the core in a single appointment.

Purpose: To evaluate the variability in shade selection for general practitioners (GPs) and postgraduate (MDS) practitioners and to assess if a shade selection bias exists.

Materials And Methods: 2070 samples of the chosen shade(s) by 31 GPs and 18 MDS practitioners in the form of work authorization forms and slips were collected from dental laboratories. The mouth was divided into four quadrants: maxillary anteriors and posteriors, and mandibular anteriors and posteriors.

Gaps and hollow spaces at the implant abutment interface will act as a bacterial reservoir that may cause peri-implantitis. Hence, the sealing ability of O-ring (in addition to polysiloxane) and GapSeal (an antibacterial sealing gel) was evaluated. A total of 45 identical implant systems (ADIN Dental Implant Systems) were divided into 3 groups of 15 implants each: an unsealed group, a group sealed with O-rings, and a group sealed with GapSeal gel.

Making impressions in microstomia patients is often cumbersome. A modification of standard impression procedure is often necessary while treating such patients. This article describes the fabrication of a custom sectional impression tray with interlocking type of a handle for definitive impression procedures in a microstomia patient.

Most endodontically treated teeth require a post-and-core build-up for restoring the teeth to optimum health and function. Selection of an appropriate post-and-core system from the wide variety of those available may be a clinical dilemma. Therefore, the purpose of this article is to review the literature to identify the various factors that influence the selection of the post-and-core assembly.

The purpose of this survey was to assess the awareness of dental practitioners relating to chair side techniques in restoring teeth with light cure composite. The survey package consisted of a consent form, a leaflet stating the rationale and purpose of the survey and the questionnaire. Randomised sample of dental surgeons in practice was selected.
