PURPOSE This in vitro study aimed to evaluate the effect of implant connection design (external vs. internal) on the fit discrepancy and torque loss of zirconia and titanium abutments. MATERIALS AND METHODS Two regular platform dental implants, one with external connection (Brånemark, Nobel Biocare AB) and the other with internal connection (Noble Replace, Nobel Biocare AB), were selected. Se...

Dental implants have been a universally accepted option for prosthetic rehabilitation of partially edentulous patients. Titanium implants abutments exhibit a dull grayish hue and give an unnatural appearance. Abutments based on zirconia are one of the alternatives to titanium abutments. To date, few comparative studies have reported on esthetic and biological outcomes of implant-supported resto...

OBJECTIVES This study was undertaken to characterize the mechanical response of bare (as-received) and single-layer ceramized zirconia abutments with both internal and external connections that have been developed to enhanced aesthetic restorations. MATERIAL AND METHODS Sixteen zirconia implant abutments (ZiReal Post®, Biomet 3i, USA) with internal and external connections have been analyzed....

The maxillary lateral incisor is the second most common congenitally absent tooth. There are several treatment options for replacing the missing maxillary lateral incisor, including canine substitution, tooth-supported restoration, or single-tooth implant. Dental implants are an appropriate treatment option for replacing missing maxillary lateral incisor teeth in adolescents when their dental a...

OBJECTIVES Head and neck cancer patients who have lost facial parts following surgical intervention frequently require craniofacial implant retained facial prostheses for restoration. Many craniofacial implant patients require computed tomography and magnetic resonance imaging scans as part of their long-term follow-up care. Consequently removal of implant superstructures and peri-abutment tiss...

OBJECTIVES The aim of this study was to assess the clinical outcomes achieved with Computer-Assisted Design/Computer-Assisted Manufacturing implant abutments in the anterior maxilla. MATERIAL AND METHODS Nineteen patients with a mean age of 41 (range form 26 to 63) years, treated with 21 single tooth implants and 21 Computer-Assisted Design/Computer-Assisted Manufacturing (CAD/CAM) abutments ...

OBJECTIVE The aim of the present study was to analyze the soft tissue barrier formed to implant abutments made of different materials. MATERIAL AND METHODS Six Labrador dogs, about 1 year old, were used. All mandibular premolars and the first, second and third maxillary premolars were extracted. Three months later four implants (OsseoSpeed, 4.5 x 9 mm, Astra Tech Dental, Mölndal, Sweden) were...

Fixed Dental Prosthesis is a treatment modality to replace the missing tooth by utilizing adjacent teeth as abutments. The health, periodontal surface area, crown root ratio and other parameters govern condition of abutment. examination these clinical radiographic determine its usage abutments support retain prosthesis. Adjunctive therapy like lengthening, foundation restorations others can be ...

PURPOSE The anterior region is a challenge for most clinicians to achieve optimal esthetics with dental implants. The provisional crown is a key factor in the success of obtaining pink esthetics around restorations with single implants, by soft tissue and inter-proximal papilla shaping. Provisional abutments bring additional costs and make the treatment more expensive. Since one of the aims of ...
