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.

Workshop Guidelines on Immediate Loading in Implant Dentistry
Predictable formation of a direct bone-to implant interface is a treatment goal in implant dentistry. The 2-stage surgical protocol established by Branemark et al to accomplish osseointegration consisted of several prerequisites, including (1) countersinking the implant below the crestal bone, (2) obtaining and maintaining a soft-tissue covering over the implant for 3 to 6 months, and (3) maintaining a minimally loaded implant environment for 3 to 6 months. The primary reasons cited for the submerged,…

Zygomatic Implant Placement in Conjuction with Sinus Bone Grafting: The "Extended Sinus Elevation Technique." A Case-Cohort Study
The zygomatic implant in mainly indicated for the rehabilitation of extremely atrophied maxillae when bone augmentation should be avoided. One Drawback of zygomatic implants, which typically pass through the sinus, is initial or late bone resorption around the implant neck, which can result in oroantral communications followed by possible infection of the sinus. To decrease the risk of sinus infection, a modified technique was developed to preserve the integrity of the sinus membrane and to regenerate bone around zygomatic implants using an extended sinus grafting approach.

A Treatment For The Prevention of Mandibular Edentulism: All On Four For The Mandible
Mandibular edentulous patients can be some of the most difficult prosthetic patients to treat successfully. Tongue and vestibular movements during function can dislodge the denture, arch forms may demonstrate poor anterior/posterior spreads, and severe resorption of the mandible can lead to mental nerve involvements with unstable denture bases for effective chewing patterns. Fixed dental prosthesis stabilized by osseointerated implants are an effective treatment option for patients who have lost their mandibular teeth.

Implant Overdentures: What You Need to Know
Implant Dentistry has evolved from the original concept of primarily treating the edentulous mandible with a retrievable fixed prosthesis. Today most dental implant cases involve partially edentulous situations treated with fixed prosthetic solutions. However the fully edentulous mandible and maxilla still comprise an important subset of our patients, and techniques for utilizing fixed and removable full arch prostheses have evolved to restore both arches.

Implant Esthetics: Recognizing Pitfalls and How to Avoid Problems
In this Webinar on Implant Esthetics, Dr Stanley describes the "No Half Smiles" philosophy that he practices. An emphasis is placed on both the clinical and technical requirements necessary for delivering consistent successful esthetic results in everyday practice. In addition, several techniques are demonstrated to make patient management through this process more efficient. As Dr. Stanley states" the challenges of getting it right are many but avoiding complications is vital to the success of our daily practice.
