Four modalities of single implant treatment in the anterior maxilla: a clinical, radiographic, and aesthetic evaluation.

Purpose: To document the outcome of single implants in the anterior maxilla following four routine treatment modalities when performed by experienced clinicians in daily practice using the same implant system and biomaterials.

Material And Methods: A retrospective study in patients who had been treated by two periodontists and two prosthodontists in 2006 and 2007 was conducted. The four treatment modalities practically covered every clinical situation and included standard implant treatment (SIT), immediate implant treatment (IIT), implant treatment in conjunction with guided bone regeneration (GBR), and implant treatment in grafted bone (BGR) harvested from the chin.

Clinical observations and success rates of palatal implants.

Introduction: Anchorage control is a challenge in orthodontics. Implants can be used to provide absolute anchorage.The aim of this study was to evaluate the success rates of palatal implants used for various anchorage purposes.

Palatal implants in adolescents: a histological evaluation in beagle dogs.

Objectives: Small osseointegrated implants inserted in the palate provide a reliable anchorage control during orthodontic treatment. When these implants are inserted in the median palatal suture in adolescents, there might be interference with normal transverse development of the maxilla. The aim of this study was to determine histometrically the influence of implants inserted in the median palatal suture in adolescent beagle dogs on transverse maxillary development and to determine the amount of osseointegration of unloaded palatal implants in the median palatal suture in adolescent beagle dogs.

Osseointegration of miniscrews: a histomorphometric evaluation.

Mini-implants and miniscrews are commonly used in orthodontics to provide additional temporary intraoral anchorage. Partial osseointegration represents a distinct advantage in orthodontic applications, allowing effective anchorage to be combined with easy insertion and removal. This article reports the histomorphometric findings of the osseointegration of bracket screw bone anchors (BSBAs).

Two-piece implants with turned versus microtextured collars.

Implant companies have been promoting two-piece implants with microtextured collars in the interest of hard tissue preservation and/or soft tissue integration. However, this rationale may not be justified. Based on comparative studies currently available, it is unclear whether microroughened implant necks reduce crestal bone loss.

Subgingival chlorhexidine varnish administration as an adjunct to same-day full-mouth root planing. II. Microbiological observations.

Background: Recently, the clinical additive value of a highly concentrated chlorhexidine (CHX) varnish, when applied subgingivally as an adjunct to scaling and root planing, was described. The objective of the present study was to investigate the microbiological impact of a treatment strategy for chronic periodontitis based on a combination of same-day full-mouth root planing and subgingival CHX varnish administration.

Methods: A randomized, controlled, single-blind, parallel trial was conducted on 33 non-smoking chronic periodontitis patients.

Subgingival chlorhexidine varnish administration as an adjunct to same-day full-mouth root planing. I. Clinical observations.

Background: Chemo-mechanical treatment concepts have been developed to improve the outcome of non-surgical periodontal therapy. Recently, the clinical additive value of a supersaturated chlorhexidine varnish was shown when used as an adjunct to staged scaling and root planing. The aim of this study was to investigate the clinical effects of a treatment strategy for chronic periodontitis based on a combination of same-day full-mouth root planing and subgingival chlorhexidine varnish administration.

Clinical benefits of subgingival chlorhexidine varnish application as an adjunct to same-day full-mouth root planing: a pilot study.

Background: Although scaling and root planing are considered the therapeutic standard for periodontitis, weakly responding sites often occur. To improve treatment outcome, several chemomechanical treatment concepts have been developed. Recently, the clinical surplus value of a highly concentrated chlorhexidine varnish has been shown when used as an adjunct to sequential scaling and root planing.

Long-term clinical effects of a chlorhexidine varnish implemented treatment strategy for chronic periodontitis.

Background: Scaling and root planing in combination with oral hygiene monitoring are still considered the therapeutic standards for periodontitis. Although this treatment concept customarily results in satisfactory clinical improvements, treatment outcome may become less favorable predominantly when full access to periodontal defects is compromised, thereby leaving accretions behind. The purpose of this study was to investigate, over a 9-month period, the clinical benefits of a treatment strategy for chronic periodontitis based on a combination of sequential scaling and root planing and subgingival chlorhexidine varnish administration.

Orthodontic anchorage implants inserted in the median palatal suture and normal transverse maxillary growth in growing dogs: a biometric and radiographic study.

Small osseointegrated implants inserted in the palate provide a reliable anchorage control during orthodontic treatment. When these implants are inserted in the median palatal suture in growing individuals, the possible effects on normal transverse maxillary growth are still unknown. Therefore, the aim of this study was to evaluate the influence of orthodontic anchorage implants on transverse maxillary growth when inserted in the median palatal suture of growing dogs.

A systematic review on the effects of subgingival chlorhexidine gel administration in the treatment of chronic periodontitis.

Background: Since scaling and root planing are not always successful, predominantly when access to periodontal defects is compromised, various antimicrobial agents as adjuncts have been suggested to enhance their efficacy. Gel vehicles delivering chlorhexidine (CHX) have become available and tested for these indications.

Methods: An electronic (MEDLINE and Cochrane Oral Health Group Specialized Trials Register) and manual search were made to detect studies concerning the use of chlorhexidine gels as a single measure of treatment and as an adjunct to scaling and root planing.

Root repair after injury from mini-screw.

Mini-implants and mini-screws are commonly used in orthodontics to provide extra anchorage. One potential insertion site is between the roots in the alveolar process, which results in a risk of damaging the roots of neighbouring teeth. In an animal-experimental study, 20 mini-screws (bracket screw bone anchors, BSBAs) were inserted into the mandible of five beagle dogs.

Short-term anti-plaque effect of two chlorhexidine varnishes.

Background: Chlorhexidine (CHX) varnishes have been mainly used for the prevention of caries in high-risk populations. Reports regarding their anti-plaque effect on a clinical level are limited to non-existing as opposed to their microbiological impact on plaque formation.

Aim: The aim of this preliminary investigation was to evaluate the anti-plaque effect of two CHX varnishes applied on sound enamel in relation to a positive control, a negative control and to one another.

A chlorhexidine varnish implemented treatment strategy for chronic periodontitis: short-term clinical observations.

Objectives: The aim of this study was to investigate the clinical outcome of a subgingivally applied chlorhexidine varnish when used as an adjunct to scaling and root planing (SRP) in the treatment of chronic periodontitis.

Material And Methods: A randomized controlled, single blind, parallel trial was conducted on the basis of 16 volunteers suffering from chronic periodontitis. The control group received oral hygiene instructions and was scaled and root planed in two sessions.

[Chlorhexidine varnishes in dentistry].

Since the discovery of chlorhexidine as a potential surface antiseptic in the fifties, it has been abundantly used in different kinds of dental pharmaceutics. During the past decade chlorhexidine containing varnishes have been added to this list. These products present several advantages in comparison to the existing chlorhexidine formulations.
