Introduction: There are mixed results regarding the aesthetic advantage of immediate provisionalization of dental implants. Therefore, this study aimed to compare facial mucosal level of single immediately placed implants with and without immediate provisionalization.
Methods: Single implants were immediately placed to replace a hopeless maxillary anterior or premolar tooth in 40 subjects. Each implant was randomly assigned to receive a non-occluding temporary crown or a healing abutment after implant placement. At 4 months, these implants were permanently restored and followed up for 12 months. Clinical and radiographic parameters were measured and compared.
Results: The implant survival rate at 12 months in the test and control group was 90% and 100%, respectively. Mid-facial mucosal marginal level and papilla height changes were minimal within groups, and no significant differences were found between the two groups. The amount of marginal bone remodelling was modest, with no significant difference between the two groups. Radiographic bone changes were not statistically different between the groups, except for the vertical crestal bone resorption.
Conclusion: Immediate implant placement with or without provisionalization can achieve stable vertical soft tissue level for 12 months as compared to pre-extraction level. However, immediate provisionalization was not able to improve the aesthetic outcome further.

Background: Robotic arm assisted total knee arthroplasty (RA-TKA) aims to improve accuracy in bone resection, implant positioning, and joint alignment compared to manual TKA (M-TKA). However, the learning curve of RA-TKA can disrupt operating room efficiency, increase complications, and raise costs. This study examines the operative time learning curve of RA-TKA using a single robotic system.

Aim The primary objective of the study was to evaluate the mid-term implant survivability, rate of revisions, and clinical and functional outcomes following patella resurfacing during total knee arthroplasty (TKA) utilizing posterior stabilized (PS) total knee system (TKS). Methods A prospective, single-arm, multi-center, post-marketing surveillance encompassed patients with end-stage primary knee osteoarthritis (OA) or inflammatory arthritis. The time points of the study included baseline, six weeks, six months, one year, and three years post-operatively.

Statement Of Problem: The impact of free gingival graft (FGG) dimensions on the postsurgical shrinkage of keratinized tissue width (KTW) and surface area in posterior implant sites is unclear. Standardized assessments of how graft dimensions influence KTW and surface area shrinkage rates over a 6-month period after FGG are lacking.
Purpose: The purpose of this prospective parallel cohort study was to examine the impact of the graft dimensions on the postsurgical shrinkage of KTW and surface area over a 6-month follow-up period after FGG in the posterior regions.
Comparison of clinical outcomes between Castor single-branched stent graft and in situ fenestration in treating Stanford type B aortic dissection involving the left subclavian artery: A retrospective case-control study.

Stanford type B aortic dissection involving the left subclavian artery (LSA) poses significant clinical challenges. The Castor single-branch stent graft and in situ fenestration are commonly used techniques, but the better endovascular treatment remains debated. This study evaluates the clinical effects of the Castor single-branched stent graft versus in situ fenestration in treating Stanford type B aortic dissection involving the LSA.
