A pier abutment is the lone standing tooth between two critically situated edentulous spaces, in a frequently seen clinical situation, missing first premolar and molar seen, which leads to design where canine second acts as terminal abutments abutment. This fulcrum may lead debonding of less retentive during function, overcome this situation non rigid connector advised. paper presents case repo...

PURPOSE This study examined the effects of the abutment types and dynamic loading on the stability of implant prostheses with three types of implant abutments prepared using different fabrication methods by measuring removal torque both before and after dynamic loading. MATERIALS AND METHODS Three groups of abutments were produced using different types of fabrication methods; stock abutment, ...

BACKGROUND Microleakage through the interface has been documented in implant systems with titanium (Ti) abutments. There is a current increase in the use of zirconia (Zi) abutments especially in esthetic zone in where higher risk of visible metal color through the peri-implant tissues exists. PURPOSE The aim of the present in vitro study is to evaluate the leakage at the implant fixture-abutm...

Parallel use of implant treatment planning software and cone-beam computed tomography (CBCT) can, using certain criteria, consolidate steps and streamline tooth replacement strategies. The authors describe such a case in the esthetic zone whereby flapless extraction and immediate implant placement using CT-guided surgery were performed simultaneously, with placement of a computer-aided design/c...

The abutment(s) of a partial fixed dental prosthesis (PFDP) should have a minimal total occlusal convergence (TOC), also called a taper, in order to ensure adequate retention of a PFDP that will be made for the abutment(s), given the height of the abutment(s). This article reviews the concept of PFDP abutment TOC and presents an alternative definition of what TOC is, defining it as the extent t...

STATEMENT OF PROBLEM Unlike screw-retention type, fixture-abutment retention in Locking taper connection depends on frictional force so it has possibility of abutment to sink. PURPOSE In this study, Bicon® Implant System, one of the conical internal connection implant system, was used with applying loading force to the abutments connected to the fixture. Then the amount of sinking was measure...

Abstract Implant-based restoration is currently seen to be a more reliable option with higher success rates. Biological and technological problems, on the other hand, are common. An implant insertion complication well known many loosening of abutment screw. Fractures implant-abutment may cause fail function efficiently as they leave fragment inside implant. This study aimed introduce modified d...

objectives : this finite element method study aimed to compare the amount of stress on an isolated mandibular second premolar in two conventional reciprocal parallel interface designs of removable partial dentures (rpds) and the same rpd abutment tooth (not isolated). materials and methods: a kennedy class 1, modification 1 rpd framework was simulated on a 3d model of mandible with three differ...

The Brånemark dental implant has undergone progressive development in terms of both the implant body itself and the components connecting the implant to the prosthesis. Many screw and abutment designs have been developed, with various degrees of success. About 15 years ago, CAD (computer-assisted design)-CAM (computer-assisted manufacture) technology was introduced to dentists. More recently CA...

The 1-piece, implant-supported abutment and crown, colloquially described as the UCLA abutment, commonly is used to fabricate single, screw-retained crowns. This abutment was designed to allow attachment of the crown directly to the implant and requires a waxing and casting procedure by a laboratory technician. A new prefabricated abutment has been developed that uses a similar approach but doe...
