Objective: Narrow alveolar ridges pose a serious challenge for successful placement of endosseous implants and alveolar ridge widening procedure is indicated in cases of crest thickness of ≤4.0 mm. The study evaluated and compared, immediate and delayed techniques of implant placement using split crest technique to augment atrophic narrow alveolar ridges.
Methods: The study was carried out in 10 patients randomly divided into two groups of five each for immediate or delayed placement of implants. Implants were placed simultaneously after split crest procedure in immediate technique and after 3-4 weeks of healing in delayed technique. Data collected was statistically analyzed by SPSS version 22 using unpaired -test, ANOVA and Pearson's correlation with p value = 0.05.
Results: Statistically significant (p = 0.000) difference was observed for implant stability at intra-op, 4 months and 6 months post-op between the two groups, however there was no statistically significant difference in amount of augmentation achieved between the two groups.
Conclusion: We observed that both the techniques were comparable on the basis of augmentation achieved, implant success and survival rates, whereas implant stability was significantly higher in delayed technique group.

Pulmonary involvement is commonly observed in anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), presenting with manifestations such as diffuse alveolar hemorrhage, inflammatory infiltrates, pulmonary nodules, and tracheobronchial disease. We aimed to identify distinct subgroups of tracheobronchial disease patterns in patients with anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) using latent class analysis (LCA), and to evaluate their clinical characteristics and outcomes. We conducted a retrospective cohort study using electronic medical records of patients aged >18 years diagnosed with AAV and tracheobronchial disease between 1 January 2002 and 6 September 2022.

Background: Gingival recession defects (GRDs) pose functional and esthetic concerns and may be associated with unfavorable tooth positions. Surgically facilitated orthodontic treatment (SFOT) with clear aligners can be a valuable option for adults with severe malocclusion and GRDs.
Methods: A 28-year-old male presented with severe dental crowding, Class III dental malocclusion, localized tooth crossbites, and tapered maxillary arch.

Article Synopsis
- The study aimed to assess the long-term outcomes of one-piece narrow-diameter implants (NDIs) and identify factors influencing marginal bone loss (MBL) around them.
- The analysis involved 25 patients and 40 NDIs over an average of 10.5 years, with a high survival rate of 95.1% for implants and a mean MBL of 0.44 mm, primarily linked to the use of guided bone regeneration (GBR).
- The findings suggest that NDIs perform well clinically over time, showing acceptable MBL, but further research with larger samples is recommended to confirm these results.

Are Bone Expansion Techniques Effective for Implant Placement in Narrow Alveolar Ridges?

Because of the fact that sufficient alveolar ridge bone is essential for the success of implant placement, the authors often face a challenge with augmenting residual maxillary alveolar ridges. The aim of the study was to compare the amount of ridge gain by the Osseodensification method with the manual bone expanders method for healed edentulous sites in the maxilla at different time intervals (immdiate postoperative and 6 mo postoperative). Two groups were equally and randomly divided with a total of 14 implants (Biohorizons) placed in the maxillary arch for 8 patients, osseodensification was used for 1 group (group 1), whereas manual threaded expanders (bone spreaders) was used for the other group (group 2).
