Influence of a Novel Surface of Bioactive Implants on Osseointegration: A Comparative and Histomorfometric Correlation and Implant Stability Study in Minipigs.

Purpose: The objective of this study was to assess the influence of a novel surface of dental implants (ContacTi) on the osseointegration process in a minipig model. The surface was compared with other existing surfaces on the market (SLA and SLActive) by employing bone implant contact analysis (BIC) and implant stability.

Method: Twelve minipigs were used with prior authorisation from an ethics committee.

Effectiveness of a new dental implant bioactive surface: histological and histomorphometric comparative study in minipigs.

Objectives: The objective of this study was to assess, by histomorphometric analysis, the degree of bone apposition on two types of dental implant's surfaces: a novel implant that combines AlO abrasive particle blasting with thermochemical treatment (ContacTi), compared to a standard surface treatment obtained by sandblasting and acid etching (shot blasting).

Materials And Methods: Twelve minipigs were used, placing the studied implants in the maxillae, and divided into three groups according to the time of sacrifice: 2, 4, and 8 weeks after implant placement. Histological and histomorphometric analyses were performed following standardized tissue polymerization, cutting, and staining and examined under optical and high-resolution electron microscope.

Influence of two different machined-collar heights on crestal bone loss.

Purpose: The purpose of this trial was to evaluate crestal bone level changes radiographically in a standardized fashion over a period of 12 months in humans for implants with a 0.7-mm machined collar (implant type A) versus type B implants with a 1.5-mm machined collar.

Intra-alveolar chlorhexidine gel for the prevention of dry socket in mandibular third molar surgery. A pilot study.

Purpose: Chlorhexidine is a good prophylactic agent for post-extraction dry socket alveolitis. The bio-adhesive 0.2% chlorhexidine gel could improve this action since its intra-alveolar positioning would allow a more direct action on the alveolus and more prolonged action of the medication.

Update on dry socket: a review of the literature.

Dry socket is a postoperative complication that occurs after a dental extraction and has been defined as an inflammation of the alveolus. If this inflammation should surpass the alveolar walls, it would result in a located osteitis. The frequency of appearance of dry socket has been reported in a very wide margin, from 1% until 70%.

Orofacial infections of odontogenic origin.

The polymicrobial nature of the odontogenic infections as well as the variety of associated conditions are a consequence of the diversity of the buccal microbiota and the anatomical and functional complexity of the oral cavity. In addition to this, all these processes can give way to multiple complications which range from the local to the systemic level. The appropriate choice of antibiotic and posology is crucial in the successful management of these infections.

Differential diagnosis and therapeutic approach to periapical cysts in daily dental practice.

The diagnosis and therapeutic approach to periapical cysts is an extremely controversial concern for dentists. Furthermore, as this complaint represents the most frequent cystic lesion of the maxilla, together with the fact that its differential diagnosis with chronic apical periodontitis presents special difficulty, the question takes on even greater importance. The purpose of this article is to assess the validity of the various diagnostic techniques used to differentiate between both pathologies and make a critical analysis of the controversy surrounding the therapeutic approach to suspected periapical cysts through non-surgical and follow-up treatment, or surgical enucleation and histopathological analysis.
