The socket-shield technique at molar sites: A proof-of-principle technique report

The socket-shield technique for avoiding postextraction tissue alteration was first described in 2010. The technique was developed for hopeless teeth in anterior esthetic sites but has not yet been described for molar sites. Managing postextractive ridge changes in the posterior region by prevention or regeneration remains a challenge. The socket shield aims to offset these ridge changes wherever possible, preserving the patient’s residual tissues at immediate implants. This technique report describes the molar socket-shield step by step.     

Lingual technique indirect [corrected] bonding: double transfer tray technique

In this article, the author analyzes the problems that can occur with the traditional technique of indirect bonding with the complete arch transfer tray, and describes step-by-step the technique of a double tray bonding technique and its advantages.     

Socket augmentation: rationale and technique

The consequences of exodontia include alveolar bone resorption and ultimately atrophy to basal bone of the edentulous site/ridges. Ridge resorption proceeds quickly after tooth extraction and significantly reduces the possibility of placing implants without grafting procedures. The aims of this article are to describe the rationale behind alveolar ridge augmentation procedures aimed at preserving or minimizing the edentulous ridge volume loss. Because the goal of these approaches is to preserve bone, exodontia should be performed to preserve as much of the alveolar process as possible. After severance of the supra- and subcrestal fibrous attachment using scalpels and periotomes, elevation of the tooth frequently allows extraction with minimal socket wall damage. Extraction sockets should not be acutely infected and be completely free of any soft tissue fragments before any grafting or augmentation is attempted. Socket bleeding that mixes with the grafting material seems essential for success of this procedure. Various types of bone grafting materials have been suggested for this purpose, and some have shown promising results. Coverage of the grafted extraction site with wound dressing materials, coronal flap advancement, or even barrier membranes may enhance wound stability and an undisturbed healing process. Future controlled clinical trials are necessary to determine the ideal regimen for socket augmentation.     

Surgical extrusion: A dental technique

This article describes a technique for surgically extruding severely compromised roots needing prosthetic rehabilitation. Unlike previously described approaches, the technique does not require advanced clinical skills or equipment, may reduce the risk of tooth or bone fracture during the luxation maneuvers, and does not seem to interfere with the alveolar socket healing process.     

Roll technique modification: papilla preservation

The aim of this article was to describe an Abrams technique's modification. Abrams' roll flap, performed at the implant second surgical stage, allows for the correction of small horizontal defects by enhancing the buccal soft tissue thickness and improves the buccal soft tissue profile. This modification preserves the papilla's morphology, reduces postsurgical discomfort, and enhances soft tissue healing and aesthetic results.     

Direct pressure provisionalization technique: a new open-tray technique for complete-arch rehabilitations.

An innovative direct technique that improves the accuracy of provisional acrylic resin restorations is introduced. A custom impression tray is modified to facilitate complete occlusal closure. This open tray is used to make an accurate overimpression prior to beginning tooth preparation procedures. Following tooth preparation, the acrylic resin-filled overimpression is returned to its intraoral position, and the patient occludes into the previously indexed impression material. The pressure overimpression technique is offered as an expedient technique for improving the accuracy of provisional restorations.     

两种窝沟封闭术疗效比较的系统评价

目的:系统评价釉质成形封闭术(enameloplasty sealant technique,EST)和普通窝沟封闭术(conventional sealant techni-que,CST)的临床疗效。方法:采用Cochrane系统评价的方法,计算机检索我国有关EST与CST的临床随机对照研究的文献,检索时间截止2010年。在严格筛选资料和质量评价的基础上,采用RevMan 5.0软件对纳入的研究进行Meta分析。结果:共检索到38篇相关文献,最终有9篇文献符合纳入标准。Meta分析结果显示,EST组术后1年新龋发生率与CST组差异无统计学意义[OR=0.45,95%CI(0.10,2.05)],其它时期防龋效果及3年封闭剂保存率均优于CST组,差异有统计学意义[OR=2.67,95%CI(1.91,3.73)]。结论:现有证据表明,窝沟釉质成形封闭术的防龋效果优于普通窝沟封闭术。     

The posterior superior alveolar injection technique: a report on technique variations and complications

The posterior superior alveolar (PSA) injection technique has varied over time with respect to the depth and angle of penetration, the location for deposition of anesthetic agent, and the number of injections necessary to assure adequate anesthesia to the maxillary molars. Of the standard intraoral injections, the PSA carries with it the second highest risk for anesthesia complications. With changes in armamentarium and technique, the complication rates have declined and more often are associated with anatomical considerations with respect to neurovascular compromise and/or anesthetic solution. In this study, the PSA injection technique and complication histories were investigated. Seventeen variations to the technique are reported along with 12 injection complications. A historic injection complication classification system is presented along with a management strategy based upon a review of reported provider experiences and treatment suggestions.
