The importance of occlusal trauma in the primary etiology of periodontal disease.

The presence of periodontal disease can be ascertained by clinical examination (redness, edema and probe depth, bleeding-on-probing). Occlusal adjustment can lead to a marked, stable improvement in periodontal health in terms of bacterial profile and clinical appearance, presumably by obviating tissue distress caused by occlusal dysfunction, thereby providing unfavorable conditions for bacterial growth. Therefore, occlusal trauma can be an essential indicator of the periodontal disease and, if not corrected, could lead to a relapse.

Rehabilitations with immediate loading of one-piece implants stabilized with intraoral welding.

The authors present an implant prosthesis procedure that uses screws on one-piece implants connected with a titanium pin at their abutment level and one supporter titanium bar in order to guarantee immediate stabilization. These can be implanted and fitted with customized temporary crowns in a single surgical procedure, restoring function and aesthetics and consenting recovery of the bone deficit with reduced healing times and limited patient discomfort. One-piece wide-diameter titanium screw implants with thread measurements of 2.

Implant Dentistry: Monitoring of Bacteria Along the Transmucosal Passage of the Healing Screw in Absence of Functional Load.

Purpose: To assess the changes in bacterial profile along the transmucosal path of healing screws placed immediately after insertion of two-piece endosseus implants during the 4-month osseointegration phase, in absence of functional load.

Materials And Methods: Two site-specific samples were collected at the peri-implant mucosa of the healing screws of 80 two-piece implants, for a total of 640 samples. Implants placement was performed following a single protocol with flapless technique, in order to limit bacterial contamination of the surgical site.

Correlation between dysfunctional occlusion and periodontal bacterial profile.

The aim of this study is to compare the evolution in bacterial profile at evident periodontitis sites following two types of treatment - oral hygiene procedures alone (Group 1) and oral hygiene plus occlusal adjustment through selective grinding (Group 2). The presence of periodontal disease was ascertained by clinical examination (redness, oedema, probe depth, bleeding-on-probing). Bacterial profiling was carried out via phase contrast microscopy on plaque samples taken from periodontitis sites in both patient groups.
