When dental implants are malpositioned in relation to the adjacent teeth and alveolar bone or in an excessive buccal or lingual position, the final prosthesis rehabilitation impairs the peri-implant health of the gingival tissues and the aesthetics of the patient. Thus, the purpose of this case was to report and discuss a multidisciplinary protocol for the treatment of a compromised maxillary t...

Background To carry out a systematic literature review of the causes of preload loss of the abutment screws, of internal and external connection implants, tightened to different torque values and subjected to cyclic loading. Material and Methods A systematic search was conducted in PubMed, EMBASE, and Cochrane Library databases with reference to in vitro studies in which internal and external...

PURPOSE To evaluate adherence of human gingival fibroblasts (HGFs) to transmucosal abutment of dental implant with different surface conditions with time and to investigate the roles of focal adhesion linker proteins (FALPs) involved in HGFs adhesion to abutment surfaces. MATERIALS AND METHODS Morphologies of cultured HGFs on titanium and ceramic discs with different surface were observed by ...

AIM Removable partial dentures (RPDs) may have a negative impact on oral health and have the potential to cause further tooth loss, especially of abutment teeth. However, no evidence indicates the effective interval of regular periodontal maintenance after RPD provision. This practice-based cohort study aimed to examine the impact of regular periodontal maintenance visits on survival of RPD abu...

PURPOSE The aim of this in vitro study was to compare the accuracy of two different impression techniques for the All-on-Four implant therapy protocol. MATERIALS AND METHODS An acrylic resin analog for an edentulous maxilla with four internal connection implants (Replace Select, Nobel Biocare) was fabricated according to the All-on-Four protocol. A total of 40 impressions were made with diffe...

Direct restorations are currently the most popular used in dental prosthodontics. Due to increased requirements for materials fabrication of fixed restorations, there is a need evaluation strength parameters these materials, including cements. The present study investigated change selected four dual-cured composite cements as function storage temperature. following were investigated: three-poin...

PURPOSE We assessed the repeatability and reproducibility of abutment teeth dental impressions, digitized with a blue light scanner, by comparing the discrepancies in repeatability and reproducibility values for different types of abutment teeth. MATERIALS AND METHODS To evaluate repeatability, impressions of the canine, first premolar, and first molar, prepared for ceramic crowns, were repea...

Dental implants have become a popular choice of treatment in replacing individual lost teeth or entire dentitions. The physical properties of high corrosion resistance, high structural strength and high melting point, suggest the retention of intact implants following most physical assaults. As the implants are machine made, they lack the individualisation required for their use as identifiers ...

Dental implants have been proven to be an effective way of restoring the masticatory ability to completely or partially edentulous patients. But when clinicians deal with undesirable implant orientation caused by poor bone conditions, an angled abutment is often the treatment of choice for prosthodontic restorations. A search of articles related to the success rate, stress analysis, and bone re...
