OBJECTIVE Provisional cements are commonly used to facilitate retrievability of cement-retained fixed implant restorations; but compromised abutment preparation may affect the retention of implant-retained crowns.The purpose of this study was to investigate the effect of abutment design and type of luting agent on the retentive strength of cement-retained implant restorations. MATERIALS AND M...

BACKGROUND Although, dental implants have been a predictable option to support several types of restorations, mechanical problems are not uncommon. Retaining and abutment screw loosenings/fractures are one of the most common technical problems. AIM To present a step-by-step technique in order to remove a broken locater abutment screw fragment. MATERIALS AND METHODS A 56-year-old, edentulous...

STATEMENT OF PROBLEM The choice of single-molar implant design is difficult because of a lack of controlled, quantitative biomechanical analyses. PURPOSE This study determined the effect of 3 single-molar implant designs on implant strains under a variety of homologous loading conditions. MATERIAL AND METHODS On each implant abutment, 4 strain gauges were placed axially at 90 degrees to eac...

BACKGROUND Fractured connections between implants and implant abutments or abutment screws are frequently encountered in a clinical setting. The purpose of this study was to investigate fracture strength using a torsion test at the interface between the implant and the abutment. METHODS Thirty screw-type implant with diameters of 3.3, 3.8, 4.3, 5.0, and 6.0 mm were submitted to a torsion test...

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, ...

INTRODUCTION Differences between the tooth and implant response to load can lead to many biological and technical implications in the conditions of occlusal forces. OBJECTIVE The objective of this study was to analyze load distribution in tooth/implant-supported fixed partial dentures with the use of resilient TSA (Titan Shock Absorber, BoneCare GmbH, Augsburg, Germany) abutment and conventio...

Introduction. One of the criteria of implant therapy success is marginal bone loss. The objective of the study was to assess the correlation between peri-implant marginal bone loss and implant-abutment connection systems used in the same patient, as well as other specific characteristics of implant treatment. The initial research hypothesis assumed that there was no difference in marginal bone ...

PURPOSE Microgaps at the implant-abutment interface allow for microbial colonization, which can lead to peri-implant tissue inflammation. This study sought to determine the marginal accuracy of three different implant-zirconium oxide (zirconia) abutment configurations and one implant?titanium abutment configuration. MATERIALS AND METHODS Three combinations of implants with custom-made zirconi...

longevity of osseointegrated implants are intensely influenced by biomechanical factors. control of these factors prevents mechanical complications, which include fracture of screws, components, or materials veneering the framework. in this study, the impact of length and threads pitch of dental implants on the stress distribution and maximum von mises stress in implant-abutment complex and jaw...

Interdental papillae regeneration remains a challenge in implant dentistry in cases in which papillae are lost following tooth extraction. This report presents an implant case with missing 1st and 2nd premolars and total papillary loss. We performed immediate provisionalization to the first premolar implant with a temporary abutment and crown, whereas the second premolar was submerged. Crown co...
