Temporal hollowing occurs to varying degrees after pterional craniotomy. The most common cause of temporal hollowing is a bony defect of the pterional and temporal regions due to the resection of the sphenoid ridge and temporal squama for adequate exposure without overhang. The augmentation of such bony defects is important in preventing craniofacial deformities and postoperative hollowness. Te...

INTRODUCTION This in vitro study evaluated the influence of composite thickness (with or without fiber reinforcement) on fracture resistance of direct restorations in endodontically treated teeth. METHODS AND MATERIALS Fifty-six intact human premolars were chosen and randomly divided into four groups (n=14). After preparation of a mesio-occluso-distal (MOD) cavities and cusp reduction, the te...

Onlay is an extra-coronal restoration usually involving same area as inlay restoration and portion of outer cuspal slope, it is indicated in cases of steep cuspal inclines as wedging force tends to direct forces not parallel to the long axis of tooth [3]. The versatile inlay and onlay restorations require meticulous care in preparation, but when properly designed are extremely useful as durable...

This paper presents a method for effectively modeling the outer surfaces of inlay/onlay prostheses restoring teeth that are partially destroyed. We exploit 3D mesh deformation techniques: direct manipulation free-form deformation (DMFFD) [9] and multiple wires deformation (MWD) [10] with three kinds of information: standard teeth models, scanned mesh data from the plaster cast of a patient's to...

Surgical treatment for diffusely diseased coronary arteries has been considered to be a relative contraindication for off pump coronary artery bypass (OPCAB) grafting. We report a case of off pump long-onlay-bypass grafting using the left internal mammary artery. To our knowledge, the long-onlay-patch grafting with OPCAB technique has not been previously described. Two sets of Octopus-3 tissue ...

Background: This study aimed to evaluate the influence of inlays/onlays and their material on stress distribution in mandibular molars with large cavities, using finite element analysis (FEA). Methods: 3D models first molar were created. Then, a mesio-occluso-distal cavity was created, cusps reduced (1.5 mm for buccal 1 lingual cusps). The restorations were: inlay, onlay that covered (B models)...

A case treated with onlay bone grafting and simultaneous osseointegrated implant insertion is reported. The patient had an oronasal fistula in the center of the premaxillary region due to failed repair of a bilateral cleft palate. Four fixtures were inserted with onlay bone grafting of the maxillary alveolar ridge. Twelve months postsurgery, one fixture was lost as a result of severe bone resor...

OBJECTIVE To determine whether patency rates after bulbar urethroplasty with buccal mucosa graft onlay differ on the basis of whether the graft is placed ventrally or dorsally. METHODS This was a retrospective single-center study of all single-stage bulbar urethroplasties performed from 2001 to 2011 by 2 surgeons in which buccal mucosa was used as an onlay graft. Failure was defined as the ne...

The aim of this study was to retrospectively investigate the outcomes of patients who underwent one-stage onlay or inlay urethroplasty using a lingual mucosal graft (LMG) after failed hypospadias repairs. Inclusion criteria included a history of failed hypospadias repair, insufficiency of the local skin that made a reoperation with skin flaps difficult, and necessity of an oral mucosal graft ur...

AIM The purpose of this study was to systematically review clinical studies examining the survival and success rates of implants placed with intraoral onlay autogenous bone grafts to answer the following question: do ridge augmentations procedures with intraoral onlay block bone grafts in conjunction with or prior to implant placement influence implant outcome when compared with a control group...
