The Socket Shield Technique with Promixal Extensions for Single-Rooted Teeth

The Socket Shield Technique with Promixal Extensions for Single-Rooted Teeth
The conventional socket shield (SS) design extends from the mesiolabial to the distolabial line angle. C-shaped SS, L-shaped SS, and proximal SS designs have proximal extensions that help to maintain the hard and soft tissue in the interproximal areas. This is beneficial for implant sites adjacent to an existing implant or an edentulous space. The most common complication of the socket sheild technique (SST) is internal shield exposure. Due to anatomical features such as a scalloped ridge shape and an oval socket shape of some teeth, the risk of complications such as internal shield exposure, inadvertent SS displacement, and fracture of the SS during implant insertion is greater in proximal shield areas. The present article describes guidelines for case selection for proximal shield extensions, along with SS preparation and the selection of implant and prosthetic components.

Root Submergence Technique, A Case Series with Follow-Up up to Seven Years

Root Submergence Technique, A Case Series with Follow-Up up to Seven Years
In the era of aesthetic dentistry, the goal is not only to provide a function to our patients but also to preserve the hard and soft tissue anatomy, to have a pleasing prosthesis. Obtaining natural aesthetics is simpler in single implant cases, however, in multiple implant prosthesis achieving natural dentition becomes a challenge. The root submergence technique (RST) is one such procedure that provides maximum preservation of the surrounding alveolar bone and soft tissue. This case series discusses the effect of a root submergence technique on preserving the periodontal tissue at the pontic site of fixed dental prostheses in the maxillary arch. The results of this clinical case series indicate that a root submergence technique can be successfully applied in the pontic site development with fixed dental prostheses, especially in the maxillary anterior aesthetic zone.

Human Histologic Analysis of Implant Osseointegration in a Healed Site Grafted with Nondemineralized Autologous Tooth-Derived Graft Material

Human Histologic Analysis of Implant Osseointegration in a Healed Site Grafted with Nondemineralized Autologous Tooth-Derived Graft Material
Human autologous tooth-derived grafts (ATDGs) were recently introduced as a source of bone substitute biomaterial. Using dentin autografts in humans was first reported in 2003. In that first report, demineralized dentin matrix granules were used as a bone substitute biomaterial for sinus augmentation. Since then, a variety of TDGs have been introduced clinically, including block or particulate forms of tooth structures with various levels of mineralization, as shown in Fig 1. In the present article, “TDG” is used as an all-encompassing term to better capture the variability of tooth-derived grafts that can contain the total root structure, dentin only, dentin and cementum, or even enamel.

Teeth First: A novel surgical treatment concept for the edentulous, acquired Class III, severely atrophied maxilla

Teeth First: A novel surgical treatment concept for the edentulous, acquired Class III, severely atrophied maxilla
Extreme atrophy of the edentulous maxilla still represents a challenge as far as prosthetic rehabilitation with implant-supported fixed (screw-type) prostheses is concerned. This is due not only to insufficient bone volume for implant placement but also to unfavorable three-dimensional inter-maxillary relationships that is caused by the pattern of bone resorption in the maxilla. In the scientific literature, there are few clinical studies describing the use of the Le Fort I osteotomy, as a 1 or 2 stage procedure, for the reconstruction of a three dimensionally severely atrophied maxilla, prior to implant placement.

Bone Augmentation in Infected Sites with Bovine-Derived Xenograft Mixed with Platelet-Rich Plasma Covered by Platelet-Poor Plasma

Bone Augmentation in Infected Sites with Bovine-Derived Xenograft Mixed with Platelet-Rich Plasma Covered by Platelet-Poor Plasma
The aim of this study was to assess the success of bone regeneration in infected and non-infected human dental defects, with respect to biological properties of bone remodeling. Histomorphometric analysis of bone biopsies was used to evaluate new bone formation, soft tissue, and residual biomaterial in infected and noninfected sites. In all samples, the biomaterial particles were surrounded by newly generated bone. Among factors that were analyzed, gender, medical state, and smoking had no significant effect on bone regeneration. Variables including tooth location, platelet concentrate, and protective membrane addition were also analyzed for their effects on bone regeneration.
