PURPOSE Facial crestal bone level and dimension determine function and esthetics of dentition and dental implants. We have previously demonstrated that ultrasound can identify bony and soft tissue structures in the oral cavity. The aim of this study is to evaluate the accuracy of using ultrasound to measure facial crestal bone level and thickness. MATERIALS AND METHODS A commercially availabl...

Pretreatment knowledge of crestal and radicular dentoalveolar zones and their associated thicknesses can improve risk assessment to meet esthetic and functional goals, particularly when discrepancies in anterior maxillary and mandibular arches exist and when an anterior protected articulation is to be achieved. This paper discusses a new classification of dentoalveolar bone phenotypes that diff...

A basic study was made to examine what extent of radiographic changes pertaining to early periodontal disease. The standardized radiography was used to assure geometrically identical radiographs. Artificial bone defects were produced by stages at the proximal bone crest using humane dry mandible. And as to when changes occurring in the bone on dental film can be recognized, visual assessment wa...

A systematic literature review and a meta-analysis of indirect sinus lift without the use of bone graft material was performed. A PubMed search was made from January 2005 to January 2012 with keywords: "sinus lift", "osteotome", "graft" and "maxillary sinus elevation". The inclusion criteria were: maxillary sinus lift technique with osteotomes with a minimum follow-up period of 5 months after s...

Pneumatization of maxillary sinus causes insufficient vertical bone volume on posterior maxilla. So the restoration of edentulous posterior maxilla with dental implants is challenging due to a deficient posterior alveolar ridge, unfavorable bone quality and increased pneumatization of the maxillary sinus.1 For maxillary sinus augmentation, the crestal approach and the lateral window approach ha...

Background. The present study was conducted to investigate the marginal bone loss around two different types of implant‒abutment junctions, called platform-switched (Implantium system) and non-platform switched (XiVE system) after two years of loading. Methods. Sixty-four implants in 49 patients were included in the study. The implants were placed in the posterior mandibular region according to...

Background and Aim: Crestal bone loss around dental implants is an inadvertent phenomenon. Many clinical measures have been proposed for this dilemma. This study was conducted to evaluate the crestal at different time periods in mandibular implant overdenture patients. The completed one year follow up timing. Materials & Methods: Total 15 patients were selected rehabilitation therapy includ...

several appliances have been used for palatal expansion for treatment of posterior cross bite. the purpose of this study was to evaluate the stress induced in the apical and crestal alveolar bone and the pattern of tooth displacement following expansion via removable expansion plates or fixed-banded palatal expander using the finite element method (fem) analysis.two 3d fem models were designed ...
