Background and Aims: According to the importance of primary stability on dental implant success and osseointegration, we intend to check and compare the stability and crestal bone loss rate between osteotomy technique and conventional implant insertion techniques.
Materials and Methods: In this study, 26 implants in anterior segment of maxilla in 13 patients were evaluated. The implants were TBR system (Toulouse, France) with 3.5 diameter and 10.5-12 mm length. The implant stability level was recorded immediately after surgery and 3 months later with Ostell mentor. The periapical radiography was taken immediately after surgery, 3 and 6 months to assess crestal bone resorption. Paired t-test and Wilcoxon signed Rank test used for data analysis.
Results: There were no statistically differences between the two treatments techniques in terms of stability (P>0.05). The mean crestal resorption was higher for the osteotomy technique 3 months after implant insertion (P<0.001) but there were no significant differences after 6 months (P=0.678).
Conclusion: Within the limitations of the current study, it can be concluded that the osteotomy it can be considered as a treatment technique in insufficient bone width.

Background and Aims: Recently, the use of the palatal process as a source of autogenous bone graft has been considered. Given the anatomical limitations of this space, the assessment of available bone in this area can play an important role in the correct treatment plan. The aim of this study was to assess the amount and density of available bone for the preparation of autogenous graft from the maxillary palatal process using CBCT (Cone Beam Computed Tomography).
Materials and Methods: This cross-sectional analytical study was conducted by collecting CBCT images from 78 patients referred to one of the maxillofacial radiology clinics in Kermanshah in 2022 and 2023. All the patients had no signs of trauma, impacted teeth, pathological lesions, cleft palate, severe periodontitis, or extensive surgery, and also had all the teeth in the area of interest (right first premolar to left first premolar) and their bone growth was completed (age over 20 years). The CBCT images were collected and analyzed using the ondemand program. Different indices such as the area of each cross-sectional slice, bone volume (main variable) were measured with the help of mathematical formula, bone density, and incisive canal diameter. In order to test the hypotheses, the Smirnov-Kolmogorov test was used to check the normality of data, and since none of our variables were normal, we used Spearman and Mann-Whitney correlation tests.
Results: This study was conducted on 78 subjects with a mean age of 43 years, 39 of whom were female and 39 of whom were male. The mean bone volume obtained was 1.84 cm3. The highest bone density was observed in the lateral incisor region and the mean incisal canal diameter was reported to be 2.68 mm. According to the results of the Spearman test, none of the variables had a significant relationship with the age variable. According to the results of the Mann-Whitney test, there was no significant difference in bone density in the lateral, canine, and premolar tooth areas between men and women. However, available bone volume was associated with gender, and this amount was calculated to be greater in men than in women.
Conclusion: According to the findings of this study, the average bone volume in the anterior region of maxilla was 1.51 cm3 and the highest bone density was in the lateral tooth region. The average incisal canal diameter was 2.68 cm3 and the available bone volume was related to gender and this value was higher in men than that of women. However, there was no difference in the bone density between men and women.

Background and Aims: Given the rapid growth of digital technologies in dentistry, assessing dentists’ awareness and attitudes toward this transformation is essential. This study aimed to evaluate the awareness and attitudes of general dentists in Yazd-Iran toward digital dentistry in 2025.
Materials and Methods: In this descriptive-analytical study, 135 general dentists in Yazd-Iran were selected through convenience sampling. Data were collected via an online questionnaire including demographic information and the questions related to awareness and attitude. Dat were analyzed using SPSS version 27 and the statistical analysis tests were Mann-Whitney, Kruskal-Wallis, and Chi-square to examine the variables.
Results: A total of 59 men and 76 women with a mean age of 31.92 ± 7.87 years participated in the study. The mean knowledge score was 7.76 ± 2.77 out of 12. Higher knowledge and a more positive attitude were significantly associated with older age, longer work experience, and male gender (P<0.05). Overall, 74.1% of participants were unaware of the well-known CAD/CAM system, 74.8% were unfamiliar with digital implant software, and 60% did not have adequate knowledge of correct application of intraoral scanners. While, 81.5% reported an overall positive attitude, only 11.9% considered their knowledge to be aligned with modern digital technologies.
Conclusion: General dentists demonstrated a moderate level of awareness and the existing knowledge gaps warrant greater attention in both undergraduate and continuing education. Enhancing knowledge among specific groups-such as younger, less experienced, and female dentists—is essential. Significant differences in attitudes were observed according to the age, gender, and years of professional experience.
