Purpose:
The aim of the present prospective and preliminary study was to compare the clinical and radiographic outcomes of 2 types of rough surfaced implants after implant placement in the atrophic posterior maxilla with sinus membrane elevation without bone grafting using the crestal approach.
Patients And Methods:
All clinical and radiographic records for 28 patients who had received 40 implants were included in the present study. The patients returned for radiographic and clinical examinations at 1, 3, and 6 months and every 6 months thereafter after implantation. Cone-beam computed tomography images were taken to evaluate the amount of bone gain in the maxillary sinus. Standardized periapical digital radiographs were taken to evaluate the changes in the crestal peri-implant bone level and peri-implant fixture radiolucency.
Results:
The Kaplan-Meier survival estimates demonstrated a 100% probability of survival to 24 months. No significant differences were found in cervical bone loss (CBL) or residual bone height (RBH) between the TS III CA group and the TS III SA group during the 2-year follow-up period after implant placement. The CBL values according to gender, implant placement region, prosthesis type, and the time of implantation were not significantly different between the 2 groups.
Conclusions:
The results of the present preliminary study demonstrate that 2 types of rough surfaced implants placed in the atrophic posterior maxilla with sinus membrane elevation without a bone graft have good clinical and radiographic outcomes.

01:14Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...
03:12Freezing Point Depression and Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...
