Patients who are edentulous lacks the mechanoreception which is mainly provided by the periodontal ligament that attaches a tooth to the alveolar bone. Mechanoreceptors are primarily present witihin periodontal ligament which provides feedback of magnitude, direction and rate of occlusal load application for sensory perception. Tactile sensibility is seen to be developed in patients who are treated with osseointegrated dental implants. This phenomenon is named as osseoperception. The aim of this article is to evaluate the available literature to find osseoperception related to dental implants. Keywords: Osseoperception, Implants.

Prosthetic rehabilitation of hemimandibulectomy patient, with an overlay denture, restores missing skeletal, dental structures, muscle imbalance, maxillomandibular relationship and occlusion. Conventional management with an acrylic ramp or guide plane guides only the non-resected side of the mandible to occlusion. This case report describes rehabilitation of a 13-year-old hemimandibulectomy patient with tooth supported transitional overlay denture.

Purpose The purpose of the present study was to investigate patients satisfaction and correlate the variability of aesthetic dental and facial measurements by the maxillary anterior teeth appearance in different gender group among Indian patients. Materials and methods The dental and facial measurements were made on 80 Indian subjects: Central incisor width/length ratio, gingival zenith displacements, the upper lip height, intercommisural width, maximum maxillary central incisal at rest and smile were measured. All the patients rated their satisfaction with the dental appearance on the visual-analogue scale. All the parameters have been analyzed with respect to gender. Results The great majority of the participants were completely satisfied with their dental appearance (p > 0.05). In the men, maximum maxillary central incisal display at rest and intercommisural width during smile showed statistical significant difference. In women, the combination of central incisor width/length ratio, intercommissural width at rest and smile, and maximum maxillary incisal display measurements were statistically significant. Conclusions Within the population tested, the results suggest that the use of aesthetic dental and facial measurement may serve as an aesthetic guideline. The gingival architecture should be considered in aesthetic anterior oral rehabilitation.

Aim: This study aims at evaluating stresses generated in a fixed tooth to implant connected fixed partial denture (FPD) by finite element method by varying implant design and position, in unilateral distal extension cases, i.e. for replacing mandibular 1 st and 2 nd molars. Materials and Methods: Four models were created, Model 1-A finite element model (FEA) model of a crestal implant-tooth connected metal ceramic FPD with pontic in 36 region. The 35 region simulated the second premolar. Model 2-A FEA model of a basal implant-tooth connected metal ceramic FPD. Model 3-A FEA model of a crestal implant in 36 region connected to tooth 35 and cantilevered posteriorly with pontic in 37 region, made of metal ceramic. Model 4-A FEA model of a basal implant in 36 region connected to tooth 35 and cantilevered posteriorly with pontic in 37 region, made of metal ceramic. A vertical force of 100N directed evenly on the nodes on the occlusal surface of each of the three crowns. The models displayed stress both numerically and by color coding. Results: On comparing models 1 and 2, the model 1 showed comparatively more stresses in crestal bone area of the implant. On comparing models 3 and 4, model 3 showed lesser von misses stress values. Conclusion: In case of tooth implant connected FPDs without any cantilevers, basal implants show better stress distribution when compared to crestal implants. In case of cantilever designs, crestal implant design showed lower stress values, but the difference in stresses were less.

Palatal defect can be repaired by reconstructive surgery and/or a dental prosthesis. We present prosthodontic rehabilitation of two partially edentulous patients, both with surgically induced palatal defect and explains how to achieve the goal for esthetics and phonetics. This also describes the fabrication of a hollow obturator by two piece method, which is simple and may be used as definitive obturator for maximum comfort of the patient. In both the above cases, since the mouth opening is restricted due to surgery, obturator prosthesis is given as two pieces retained with opposite poles of magnet, which facilitates the removal and insertion of the prosthesis.
