Clinical and radiographic study to evaluate marginal bone
level around one piece and two piece of immediate loaded implants
Objectives: The aim of this study was to evaluate clinically and radiographically marginal bone level around one piece and two pieces of immediate loaded implants Methods: A group of 22 patients were selected from Outpatient Clinic, Department of Oral Medicine, Periodontology, Oral Diagnosis and Oral Radiology, Faculty of Dental Medicine, (Boys, Cairo), Al-Azhar University. Patients were divided into two groups ; The study group (Group 1): included 11 patients ranged in age (between 18 -42 years old with a mean age 34.3± 4.6) received immediate loaded implant placement using one piece implants. The control group (Group 2): included 11 patients ranged in age (between 30 -38 years old with a mean age 36± 2) received immediate loaded implant placement using two piece implants. Patients were evaluated clinically at 3, 6, 9 months postoperatively and CBCT were recorded at baseline , 3, 6, and 9 months postoperatively. CBCT scan was done on Planmeca Promax 3D Mid Proface (Helsinky, Finland). CBCT scanner with following values 90 Kv, 12.5 mA, voxel size 200 micron, FOV 8 cm 8cm, All data was imported to Planmeca Romexis 5.3.1 R software. The significance level was set at (p ≤0.05). The data were collected, computed, tabulated and statistically analysed by independent t test (for comparison between the two groups) and ANOVA t test with Tukey’s post hoc test (for comparison between subsequent readings within the same group) using statistical package of scientific studies (SSPS) version 18.0. Results: It was found that buccal crestal bone level in one piece group was significantly decreased than two piece group at 3 ,6 and 9 months. Data are presented in Table (1). ( Fig. 1,2,3 and 4). At 3 , 6 and 9 months; there was non-statistically significant change in mean Bone density between the one piece and two piece implants . Data are presented in Table (2). It was also found that the peri-implant PD was decreased significantly in one piece group compared to two piece group. Data are presented in Table (3). Conclusions: Within the limits of the present study; immediate loading of two piece dental implants appeared significantly superior than one piece type
