Labial Bone Thickness in Area of Anterior Maxillary Implants Associated with Crestal Labial Soft Tissue Thickness
Soft tissue problems (ie, gingival recessions) are common in implantology and are often associated with thin soft tissue biotypes or buccally placed implants. Goaslind described 2 types of biotypes commonly found in the natural dentition: thick and thin. It has been suggested that thicker soft tissue biotypes are associated with less tissue recession, higher crestal bone levels, and better aesthetics. A thin tissue biotype has been shown to be more prone to tissue recession. Gingival recession is always associated with alveolar bone dehiscences. Furthermore, there is evidence that thick soft tissue may be protective against crestal bone loss (ie, tissue thickness of ,2.5 mm resulted in crestal bone loss of 1.45 mm vs. thicker tissues had 0.26 mm). This protective effect occurred, despite the supracrestal position of the implant-abutment interface.
Two Immediate Temporization Methods Exemplified: Flap vs. Punch Technique in Implant Surgery
Protocols and techniques for immediate tooth replacement in the esthetic zone have become more popular and predictable within the past decade. Two different clinical scenarios are presented where immediate temporization of implants placed into healed or augmented ridges is exemplified. The benefits of augmentation prior to implant placement and temporization are that flap elevation is not required; therefore, the blood supply to the labial plate is not compromised, thereby eliminating potential midfacial recession. In addition, the soft tissue subgingival shape of the temporary crown can be non-surgically sculpted at the time of implant placement since the patient is already anesthetized.
Bone Regeneration and Tissue Acceptance of Human Fascia Lata Grafts Adjacent to Dental Implants
The biologic principle of guided tissue regeneration (GTR) has been studied extensively in hopes of regenerating alveolar bone. Various materials have been utilized as regenerative membranes; however, all materials have disadvantages, and the ideal membrane material is yet to be identified. In this case report, human freeze-dried fascia lata strips were used as a regenerative barrier membrane in conjunction with the placement of endosseous root implants and demineralized, freeze-dried bone allograft.…
Revisiting the Papilla in 2016 - Part 2 of 2
In dental esthetics the regeneration of a compromised papilla , remains the most complex aspect of any reconstructive endeavor. The original 5mm Rule was found to exist only for a papilla bordered by 2 teeth and was expanded into a classification of 6 Types dependent on alternative adjacent support.e. implants or pontics.
What Tissue Changes Can We Expect with Anterior Implant Therapy?
Minimizing soft tissue changes following anterior implant therapy is one of the holy grails in implant dentistry. Gingival recession will not only impact the patient’s esthetics, the difficulties in correcting such problem create further challenges to the clinicians.
This presentation will focus on how much soft tissue changes can be expected following implant in the esthetic zone. Discussion will be made as to the etiology of gingival recession and what we can do to prevent it from happening.
Integrative Management of the Gummy Smile: Lip repositioning, Crown Lengthening & Restorative Nuances
The gingival smiles can be mild, moderate and severe , according to the degree of gingival exposure while smiling . Depending on the etiology of the problem , mild and moderate gummy smiles can be treated with moderate periodontal plastic surgery , however for severe , this procedure is not enough .
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.
Prosthetic Soft Tissue Development From Single to Full Arch Reconstruction
In addition to surgical intervention is the creation of the specific emergence profile that is essential in the aesthetic zone. The emergence profile composed of 2 parts, the abutment and the subgingival part of the crown. The shape of abutment can be individually shaped so that it gives natural appearance and varies individually (depending on the depth, angulation and diameter of the implant). Sometimes it even dictates the implant position. From a surgical perspective, soft tissue height, position and thickness need to be diagnosed and corrected when needed. From the prosthetic point of view, the emergence profile has to be created to mimic the natural appearance and maintained over time in respect to the biological changes. The course teaches step by step how to be successful with implant prosthetics from single tooth, partially edentulous to full arch reconstruction.
A Defined Algorithm for Regenerative Success Part 1
In the rapidly changing world of bone regeneration, biotechnology has taken the forefront. Bioengineering, bioactive materials, recombinant and autologous growth factors have changed the landscape of wound healing and reduced the morbidity of our regenerative procedures.
Additionally, technology related to surgical armamentarium has also changed with the advent of Piezoelectric and micro surgical tools aimed at reduced trauma and efficiency.
Grafting materials, membrane technologies, tenting screws, ti-mesh etc. have also played an integral role in the changing face of regenerative therapies.
This program will cover Site Development and Optimal Regenerative Technologies and Techniques in Implant Dentistry both prior to and at the time of implant placement.
