Purpose: To evaluate the measurement accuracy by multi-slice spiral CT(MSCT) and dental software as a tool for preoperative design before tooth implantations.
Methods: Twenty volunteers with marker template underwent MSCT. The diameter of the front teeth crowns in the bucco-lingual direction were measured by MSCT using a standard dental software package. Postoperatively, the same distances were clinically measured using a sliding caliper. The consistency between the two measurements was analyzed by paired t test using SPSS17.0 software package.
Results: The difference of measurements was -0.04-0.21mm. There was no significant difference between the CT and the manual measurement of the crown diameter in the bucco-lingual direction(P>0.05).
Conclusions: The results demonstrate that MSCT and marker template promises to be a valuable method for the measurement of jaw implant regions.

Objectives: To study the clinical effect of the L-shape technique combined with concentrated growth factor on the horizontal bone defects of maxillary anterior teeth.
Methods: Twenty-five implants from 25 patients who underwent single maxillary anterior tooth implantation with simultaneous bone grafting were selected as the study subjects. Based on the bone grafting techniques, the patients were divided into a test group (L-shaped technique with guided bone regeneration combined with concentrated growth factor, 11 cases) and a control group (traditional guided bone regeneration combined with concentrated growth factor, 14 cases).

Objectives: The aim of the present study was to investigate, whether polyetherketoneketone (PEKK) secondary crowns could be considered as alternative to gold standard in terms of their physical properties and manufacturing costs.
Methods: An upper jaw model with six implants was used. Frameworks with either 6 PEKK- or 6 electroplated secondary crowns were cemented in a wear simulator.

Objectives: To assess the effect of occlusion and implant number/position on stress distribution in Kennedy Class II implant-assisted removable partial denture (IARPD).
Materials And Methods: IARPDs were designed in six models: with one implant (bone level with a platform of 4 mm and length of 10 mm) at the site of (I) canine, (II) between first and second premolars, (III) first molar, (IV) second molar, or two implants at the sites of (V) canine-first molar, and (VI) canine-second molar. A conventional RPD served as control.

Department of Oral and Maxillofacial Surgery, Ordu University, Cumhuriyet Yerleşkesi Cumhuriyet Mahallesi, 52200, Ordu, Türkiye, Turkey.
Background: This study evaluates the efficacy of carbon fiber reinforced Polyetheretherketone (Cfr-PEEK) in fixation after sagittal split ramus osteotomy (SSRO) by comparing it with titanium in vitro.
Methods: Twenty-eight sheep hemimandibles were randomly assigned to four groups for SSRO surgery. Fixation was performed with a 4-hole titanium mini plate for 5 mm advancement in Group 1, with a 4-hole Cfr-PEEK mini plate for 5 mm advancement for Group 2, with a 4-hole titanium mini plate for 10 mm advancement for Group 3, and with a 4-hole Cfr-PEEK mini plate for 10 mm advancement for Group 4.
