Summary:

When performing conventional crown lengthening, the existing margins of an old restoration or the cementoenamel junction (CEJ) of a non-restored tooth are used to determine necessary bone removal to establish adequate space for biologic width. Creating proper space for biologic width ensures that the new margin will not infringe upon the periodontal complex and reduces the likelihood for future inflammation. One significant problem of this procedure is that, at times, significant bone must be removed. This can weaken the stability of the tooth or create a weakened and vulnerable furcation area. The more bone removed in the furcation, the greater the likelihood of future problems with maintenance. It is critical to preserve as much bone as possible to support the tooth, especially in the furcation area.

Post-Traumatic Treatment of Maxillary Incisors by Immediate Dentoalveolar Restoration with Long-Term Follow-Up

Post-Traumatic Treatment of Maxillary Incisors by Immediate Dentoalveolar Restoration with Long-Term Follow-Up
Replacing both missing maxillary interior teeth is particularly challenging, especially in compromised sockets. The case report describes the management of an 18-year-old female patient, who suffered avulsion of both maxillary central incisors at 7 years of age. The multidisciplinary implant technique, called Immediate Dentoalveolar Restoration (IDR), included extraction of the injured teeth and a single procedure for immediate implant placement and restoration of the compromised sockets after root fracture and peri-apical lesion development were detected during orthodontic treatment. Successful esthetic and functional outcomes and reestablishment of the alveolar process after bone reconstruction were observed during the 3-year follow-up period. The predictable esthetic outcomes and soft and hard tissue stability that can be achieved following IDR are demonstrated.

Coverage of Gingival Recession Defects Using Guided Tissue Regeneration With and Without Adjunctive Enamel Matrix Derivative in a Dog Model
The results of the present investigation suggest that the adjunctive use of EMD with GTR promotes formation of new bone and cementum without root resorption in recession-type defects in dogs.

Buccal Sliding Palatal Pedicle Flap Technique for Wound Closure After Ridge Augmentation

Buccal Sliding Palatal Pedicle Flap Technique for Wound Closure After Ridge Augmentation
One standard approach for wound closure after ridge augmentation is coronal flap advancement. Coronal flap advancement results in displacement of the mucogingival junction and reduction of the vestibulum. In the maxilla, a buccal sliding palatal flap can be applied for primary wound closure after ridge augmentation. The dissected part of the palatal connective tissue is left exposed, thus eliminating or reducing the amount of the coronal flap advancement respectively and increasing the amount of keratinized gingiva. In combination with guided soft tissue augmentation, this flap design enables a three-dimensional peri-implant soft tissue augmentation.

Treatment of the Mesial Concavity of Maxillary 1st Bicuspids in Comprehensive Periodontal and Restorative Cases
This video will discuss one of the most difficult areas to treat definitively, the mesial concavity of maxillary 1st bicuspids. Techniques will be evaluated whereby the surgeon can treat the cause of periodontal problems rather than the effects. A step by step presentation of removal of the concavity and the proper restoration of the post treated root surface will be shown.

The Biomimetic Approach to Saving Teeth: Minimally Invasive Restorations and Periodontal Surgery Premium Member Content

The Biomimetic Approach to Saving Teeth: Minimally Invasive Restorations and Periodontal Surgery
Stress reduced composite restorations now play a significant role in minimally invasive restorative dentistry. When combined with micro-periodontal surgical grafting techniques to alter gingival levels these procedures save teeth and warrant further consideration in our daily treatment. Our ability to minimize tooth reduction during tooth preparation and still maintain a strength of material and of bonding on previously exposed root surfaces as well as endodontically treated teeth is the future of a truly biomimetic approach. This presentation highlights this biomimetic approach to treatment and showcases the clinicians ability to provide long term management of both function and esthetics. It should open our eyes to the potential of maintaining the dentition of our patients rather than crown or implant replacement.

Zero Bone Loss Protocol: Influence of Vertical Soft Tissue Thickness on Crestal Bone Stability Premium Member Content

Zero Bone Loss Protocol: Influence of Vertical Soft Tissue Thickness on Crestal Bone Stability
Crestal bone stability is considered to be important for bone preservation, longevity of implants and to prevent peri-implant tissue recession. Implant placement level is important for bone stability. Mucosal tissue thickness was shown to be the factor having impact on bone stability. It was showed that platform switching does not reduce crestal bone loss, if soft tissues at the implant placement are thin. It is suggested that thin tissues might be thickened during implant placement, thus reducing bone resorbtion. 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.

Modern Implant Dentistry: Rules of Engagement in the Esthetic Zone - Part 2 of 2 Premium Member Content

Modern Implant Dentistry: Rules of Engagement in the Esthetic Zone - Part 2 of 2
This presentation will focus on the interdisciplinary relationship of the restorative dentist, periodontist and orthodontist to reconstruct the soft tissue foundation for all of these restorative options in anterior tooth replacement. The diagnosis of deficiencies as well as the varied treatment options will be discussed in detail. This includes periodontal crown lengthening, esthetic periodontal plastic soft tissue grafting procedures as well as prescription adjunctive orthodontic tooth movement to manipulate the soft tissue foundation prior to or subsequent with the restorative options of implants, bridges, or pontic replacement.

Surgical Veneer Grafting Protocol: Step-by-Step Utilization in the Esthetic Zone
In the lecture, are discussed all the parameters to achieve the correct diagnosis of the socket and the various treatment plan correlated to each anatomical type of socket. The Dual Zone approach (bone zone and tissue zone) will be evaluated and discussed in detail, regarding each of their variables. In the surgical part, it will be described the criteria necessary for successfully utilizing minimally invasive protocols within the esthetic zone and the possibility of placing or not placing a bone graft in the “gap” and the opportunity to use a connective tissue graft to overbuild the site bucco-lingually, performing the Surgical Veneer Grafting Protocol, idea'ed by the Agnini brothers.
