OBJECTIVES The aim of this study was to compare the aesthetic outcome of single implants in extraction sockets and healed ridges of the anterior maxilla by means of the pink aesthetic score/white aesthetic score (PES/WES) index. MATERIALS AND METHODS This retrospective study was based on data from 103 patients (43 males, 60 females) aged 24-65 years (mean(More)
The use of autogenous bone grafts is considered to be the best choice for reconstructive surgery. In the periodontal literature, the utilization of osseous coagulum was suggested by the end of the sixties. The purpose of this study is to consider the use of bone collectors (bone traps) as an alternative method for obtaining material to fill small bone(More)

This study investigated changes in the roughness parameters (Sa in μm2 and Ra in μm) of yttrium-stabilized tetragonal zirconia polycrystal (Y-TZP) and large-grit sandblasted acid-etched (SLA) titanium (TI) materials after decontamination by erbium chromium-doped:yttrium, scandium, gallium, and garnet (Er,Cr:YSGG) laser irradiation. Twenty disks were(More)
This prospective 3-year follow-up clinical study evaluated the survival and success rates of 3DP/AM titanium dental implants to support single implant-supported restorations. After 3 years of loading, clinical, radiographic, and prosthetic parameters were assessed; the implant survival and the implant-crown success were evaluated. Eighty-two patients (44(More)
OBJECTIVE This study investigated the osteoblastic behavior to yttrium-stabilized tetragonal zirconia polycrystal (Y-TZP) surface after different intensities of erbium, chromium-doped:yttrium, scandium, gallium, and garnet (Er,Cr:YSGG) laser irradiation treatment. MATERIALS AND METHODS Y-TZP blocks were randomized divided into 4 groups to Er,Cr:YSGG laser(More)
The objective of this study was to investigate how a low-intensity laser affects the stability and reverse torque resistance of dental implants installed in the tibia of rabbits. Thirty rabbits received 60 dental implants with the same design and surface treatment, one in each proximal metaphysis of the tibia. Three groups were prepared (n = 10 animals(More)
The experimental units consisted of 20 disks (n=5 per group). Ten disks of yttrium-stabilized tetragonal zirconia poly crystal (Y-TZP) (AS Technology Titanium FIX, São José dos Campos, Brazil) with 5 mm diameter and 3 mm high were standardized from CAD-CAM blocks. Ten disks with 5 mm diameter and 4 mm thickness of titanium sandblasted acidetched surface (AS(More)
