Summary:

Background: Following tooth extraction and immediate implant installation, the edentulous site of the alveolar process undergoes substantial bone modeling and the ridge dimensions are reduced.
Objective: The objective of the present experiment was to determine whether the process of bone modeling following tooth extraction and immediate implant placement was influenced by the placement of a xenogenic graft in the void that occurred between the implant and the walls of the fresh extraction socket.
Material and methods: Five beagle dogs about 1 year old were used. The 4th premolar in both quadrants of the mandible (4P4) were selected and used as experimental sites. The premolars were hemi-sected and the distal roots removed and, subsequently, implants were inserted in the distal sockets. In one side of the jaw, the marginal buccal-approximal void that consistently occurred between the implant and the socket walls was grafted with Bio-Oss Collagen while no grafting was performed in the contra-lateral sites. After 6 months of healing, biopsies from each experimental site were obtained and prepared for histological analyses.
Results: The outline of the marginal hard tissue of the control sites was markedly different from that of the grafted sites. Thus, while the buccal bone crest in the grafted sites was comparatively thick and located at or close to the SLA border, the corresponding crest at the control sites was thinner and located a varying distance below SLA border.
Conclusions: It was demonstrated that the placement of Bio-Oss Collagen in the void between the implant and the buccal-approximal bone walls of fresh extraction sockets modified the process of hard tissue healing, provided additional amounts of hard tissue at the entrance of the previous socket and improved the level of marginal bone-to-implant contact.

Advantages of the Root Submergence Technique for Pontic Site Development in Esthetic Implant Therapy
This article suggests a strategy to provide a more predictable protocol for esthetic implant treatment for multiple- tooth defects using the root submergence technique (RST). The RST maintains the natural attachment apparatus of the tooth in the pontic site, which in turn allows for complete preservation of the alveolar bone frame and assists in the creation of an esthetic result in adjacent multipletooth- replacement cases.

Ridge Splitting and/or GBR - Maxilla vs. Mandible - Part 1 of 2
Mandibular ridge splitting has been a clinical challenge due to high density of cortical bone. Therefore, some clinicians recommends two stage approach to overcome this issue. We will also present an unique ridge splitting technique that is easy to do and predictable using one stage approach.

CBCT-Guided Implantology- Improving the Accuracy and Success of Tooth Replacement
The integration of cone beam technology and 3D imaging has advanced the practice of digital dentistry. CT-guided implant planning combined with the use of a Computer Guided Surgery (CGS) implant placement kit leads to increased precision, accuracy and efficiency of implant placement. To realize the full advantages of CT guided surgery, it is important to have a thorough understanding of software and workflow, as well as the specific components of the Guided Surgery kit and their use. This session will demonstrate how the merging of implant planning software, CAD/CAM technology and CGS is enabling surgeons and restorative dentists to leverage the benefits of digital dentistry

Tissue Engineering and Platelet Derived Growth Factors: Evidence Based Therapy
Platelet derived growth factors are now routinely utilized in reconstructive therapy. This presentation describes very detailed and evidence based guidelines for clinicians interested in enhancing their abilities in tissue engineering, especially as it relates to bone augmentation. Specifically, while successful bone augmentation requires the standard surgical parameters of space maintenance, low pressure on the grafts and tension-free flap closure, optimization of this goal requires management and enhancement of the local biological conditions with growth factors. Towards that end, platelet concentrates through the constant release of growth factors are able to promote and enhance new vascularization, provide plasma protein, normal lipidemia, as well as increased collagen and fibrin activity.
