Summary:
In postextraction protocols for delayed short, medium, and long-term implant placement, it is essential to develop treatments that accelerate regeneration of the soft tissue as well as alveolar bone with the purpose of reducing the patient's waiting time and improving the quality of tissue obtaining a sufficient quantity (densities greater than 500 Hounsfield units)and quality (type II and III) of alveolar bone both inside and, more interestingly, surrounding the walls of the alveolus which insures initial stability of implants in a time frame of 8-12 weeks compared to 12 months described in the standard Branemark protocol. The treatment of postexatraction sites with PRGF and autologous fibrin is a simple, economical and predictable biotechnological procedure for the obtention of alveolar bone and keratinized tissue with significant reduction in waiting time for the patient without any adverse effects.

Using an Acellular Dermal Matrix for Increasing Keratinized Tissue Around Dental Implants
In previously published articles, investigators concluded that gingival recession may affect up to 90% of the population. Gingival recession ranges from one to three millimeters and is predominantly noted on the buccal surfaces of molar, premolar, and lower incisor teeth. Although surgical grafting techniques have traditionally been used to restore these recession sites, an acellular allograft material has recently been developed for increasing the zone of keratinized tissue surrounding teeth and…

A Review of Dental Suturing for Optimal Soft-Tissue Management
Establishing nontension primary wound closure of various softtissue flaps is paramount for optimal postsurgical wound healing. Surgical procedures that require clinical flap manipulation such as those used with traditional periodontal therapy, periodontal plastic cosmetic surgery, hard- and soft-tissue regeneration, and the excision of pathologic tissue also require excellence in execution and thorough understanding of the various techniques of surgery, suturing, and the materials currently available to…

The Basics of Root Coverage Surgery with Acellular Dermal Grafts: A STEP-BY-STEP Live Patient Demonstration
Soft tissue grafting is rapidly playing a larger role in restorative, esthetic, and reconstructive dentistry. While conventional grafting techniques have several limitations, newer grafting materials and techniques make it easier for patients to say "yes" to the treatment they truly need and desire. In this webinar, Dr. Wong will perform a step-by-step demonstration using Perioderm to correct multiple gingival recession defects. Soft tissue allografts are quickly becoming a "game changer" in dentistry, making optimum dentistry more than an ideal... it's a reality.
