Summary:

Predictable tissue regeneration presents a considerable challenge in the surgical treatment of gingival tissue defects. Soft-tissue augmentation procedures to increase the existing or create a new zone of attached keratinized gingival tissue have classically been performed using the patient's own masticatory mucosa and, more recently, using an acellular dermal allograft as the donor material. This article presents a clinical case whereby an acellular dermal allograft was placed on the buccal surface of one mandibular cuspid while a masticatory mucosal graft taken from this patient was placed in a similar fashion on the contralateral mandibular cuspid. Soft-tissue biopsies were obtained from each grafted area 12 weeks after placement, at the time of light and scanning electron microscopy (SEM) evaluation. This initial investigation demonstrated that the acellular dermal alloplastic graft material displayed clinical and histologic features that were similar to the patient's own palatal donor material when used to increase the zone of attached keratinized tissue.

Esthetic Correction of Gingival Recession Using a Modified Tunnel Technique and an Acellular Dermal Connective Tissue Allograft
Esthetic correction of gingival recession is an important goal of periodontal therapy. This article describes a surgical technique that combines a modified tunnel technique and an acellular dermal connective tissue allograft. With the aid of vertical incisions, a tunnel is created under the buccal mucosa of the affected tooth. These incisions enable easy access for graft placement and create mobility for gingival coronal positioning. The use of an accelular dermal connective tissue allograft eliminates the need for a surgical palatal donor site. This minimizes post-surgical complications.

A Novel Approach to Root Coverage: The Pinhole Surgical Technique

A Novel Approach to Root Coverage: The Pinhole Surgical Technique
Free connective tissue graft techniques are currently considered the most predictable surgical method for root coverage. However, morbidity associated with secondary graft sites has generated interest in other methods. The purpose of this study was to investigate the feasability of a novel surgical approach to root coverage: the pinhole surgical technique (PST). The retrospective study examined the results of PST used for 43 consecutive patients on 121 recession sites, of which 85 were Class I or II and 36 were Class III. The documented results indicate that PST holds promise as a minimally invasive, predictable, effective, and time and cost-effective method for obtaining optimal patient-based outcomes.

Advantages of the Root Submergence Technique for Pontic Site Development in Esthetic Implant Therapy

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.

Hard and Soft Tissue Augmentation: Optimizing Esthetic Results for the Restorative Dentist
Contemporary patient expectations have made esthetics a major requisite of all treatment plans, especially in situations where there is a high smile line. Although new restorative materials have highly improved predictability and esthetic outcomes, soft and hard tissue management play a fundamental role when working in esthetic areas. To achieve ideal esthetics, preservation of the natural soft and hard tissue architecture is a primary clinical objective. These new proposed techniques illustrate the importance of pre-prosthetic soft and hard tissue management when working in highly esthetic compromised areas.

Zero Bone Loss Protocol - Part I: Influence of Vertical Soft Tissue Thickness on Crestal Bone Stability
It is suggested that thin tissues might be thickened during implant placement, thus reducing bone resorption. The role of soft tissue thickness is well established in aesthetic treatment. It is known that thin soft tissues present an unfavorable situation for implant placement, crestal bone stability and subsequent prosthetic treatment.

From Extraction to Prosthetic Restoration: Considerations for the Esthetic Zone
This webinar will highlight surgical and restorative techniques to accomplish predictable outcomes in the esthetic zone with implant therapy. Treatment modalities will be demonstrated with high quality photography and case series discussion. Surgical modalities presented will include ridge preservation, the current evidence on the use of growth factors such as PRP and hr-PDGF bb. Also timing of implant placement as well as soft and hard tissue augmentation will be discussed. Special emphasis will be placed on immediate provisionalization of implants to accomplish optimal peri-implant mucosa architecture. Techniques to transfer provisional emergence profile to the final restoration will be presented.
