Aims: To assess the success rate and implant stability changes of narrow dental implants (NDIs) during the osseous healing period. Materials and methods: This prospective observational clinical study included 21 patients with narrow alveolar ridge of restricted mesiodistal interdental span who received NDIs. The alveolar ridge width was determined by the ridge mapping technique. Implant stability was measured using Periotest® M immediately after implant insertion then after 4 weeks, 8 weeks and 12 weeks postoperatively. The outcome variables were success rate and implant stability changes during the healing period. The statistical analysis included one-way analysis of variance (ANOVA) and Tukey\'s multiple comparisons test, values < 0.05 were considered statistically significant. Results: Twenty-one patients received 54 implants, the success rate was 92.6% (50/54). The mean ± SD periotest value (PTV) was significantly increased at 4 weeks (7.62 ± 6.39 PTV) compared with primary stability (1.48 ± 3.16 PTV), at 8 weeks (4.46 ± 4.45 PTV). It significantly decreased compared with that at 4 weeks and at 12 weeks (1.82 ± 3.22 PTV); it decreased significantly compared to that at 8 weeks. Conclusion: Narrow dental implants have a high early success rate. The implant stability during the healing period drops significantly in the first 4 weeks postoperatively and then increases steadily in the following weeks to reach to a level close to that of primary stability after 12 weeks. Clinical significance: Narrow dental implants are indicated in cases of insufficient alveolar bone width obviating the need for bone augmentation and reduced interdental space such as in cases of congenitally missing teeth or after orthodontic treatment. Knowledge of the stability changes during the osseous healing period enables the clinicians to determine the optimum time for functional loading.
The current research seeks to identify mono-multi Vision and its relation to the psychological rebellion and personality traits of university students. To achieve this aim, the researcher has followed all the procedures of the descriptive correlational approach, as it is the closest approach to the objectives of the current research. The researcher has determined his research community for Baghdad University students for the academic year 2019-2020. As for the research sample, it was chosen by the random stratified method with a sample of (500) male and female students. In order to collect data from the research sample, the researcher adopted a mono-multi-dimensional scale

Background: The denture base inaccuracies during processing negatively influence the retention and stability of finished complete denture. The aims of this study were to evaluate teeth movement and palatal adaptation of autoclave cured denture bases and their relationship with palatal depths and investments. Materials and methods: A nightly maxillary complete dentures prepared, processed and organized to be tested as follows: 1. Processing methods: water bath and autoclave with both fast and slow cycles. 2. Palatal depth: shallow, medium and deep. 3. Investing medium: stone and silicone. For every finished denture, two measurements were done: first: teeth movement by attaching metallic reference screws on the right and left centrals, first
