THIS STUDY REPORTS ON THE histological findings of two immediately loaded titanium plasma-sprayed (TPS) implants, retrieved for a fracture of the abutment and for psychological reasons, after 8 and 9 months of loading, respectively. The microscopical analysis showed that mature, compact, cortical bone was present around both implants, with the bone implant(More)
Aim of this study was to evaluate peri-implant tissue reactions to immediately loaded titanium plasma-sprayed implants in Macaca fascicularis monkeys. A total of 48 titanium plasma-sprayed implants were inserted (24 in the posterior maxilla and 24 in the posterior mandible). A metal superstructure was cemented 3 days after implant insertion on 24 implants(More)
A high prevalence of Actinobacillus actinomycetemcomitans (Aa) in subgingival plaque in patients for orthodontia already has been observed. The present study had the following aims: 1) to ascertain a direct relationship between the orthodontic appliance placement and the subgingival colonization by Aa, and 2) to determine whether the Aa growth specifically(More)
BACKGROUND This randomized controlled clinical trial was designed to compare the clinical outcomes of guided tissue regeneration with calcium sulfate graft and membrane (CS) versus guided tissue regeneration with collagen membrane (CM) or open flap debridement (OFD) only in terms of clinical attachment gain in periodontal intrabony defects. METHODS(More)
BACKGROUND The use of locally delivered antibacterials containing chlorhexidine (CHX) was proposed to improve the effectiveness of non-surgical periodontal treatment. The present multicenter randomized study investigated the effects of a xanthan-based chlorhexidine (Xan-CHX) gel used as an adjunct to scaling and root planing (SRP) in the treatment of(More)
BACKGROUND Early implantation may preserve the alveolar anatomy, and the placement of a fixture in a fresh extraction socket helps to maintain the bony crest. Although a number of clinical studies exist, no histological reports show the outcome of implantation in fresh extraction sockets without the use of membranes in humans compared to implants placed in(More)
BACKGROUND Many surgical techniques have been proposed for the correction of dental root exposition. Among these, bilaminar techniques (BTs) have been reported as offering the best results in terms of root coverage (RC). However, BTs require a second surgical site to harvest the graft, with discomfort for the patient. The use of an acellular dermal matrix(More)
The authors compared the clinical results obtained in gingival recession correction treatment using free gingival and bilaminar connective subpedicle grafts. 35 patients were treated with free gingival grafts (Group A) and 35 with subpedicle grafts (Group B). Class I and II Miller gingival recessions were chosen for treatment by the 2 procedures. The degree(More)
BACKGROUND Ginigival recession can be successfully treated with coronally positioned flaps. Twelve-month data failed to demonstrate that topical application of enamel matrix derivative (EMD) used in combination with the coronally positioned flap enhances clinical outcomes of the surgical technique used alone. This study was designed to examine the effects(More)
The cleanliness of titanium dental implants surfaces is considered to be an important requirement for achieving osseointegration, and it has been hypothesized that the presence of inorganic contaminants could lead to lack of clinical success. Aluminum ions are suspected to impair bone formation by a possible competitive action to calcium. The objective of(More)
