Adjunctive orchestrated orthodontic therapy.

The altruistic goal of any cosmetic dental rehabilitation is the re-establishment of a healthy maintainable aesthetic functional interface from an otherwise damaged dentition. To this end, a multi-disciplinary treatment plan is necessary to fulfill the periodontal, orthodontic, maxillofacial and cosmetic requirements for a healthy, stable dentition that has a favorable long-term prognosis. This comprehensive treatment approach strives for the constituent components of the dentition to have a proper occlusal scheme with properly aligned and positioned teeth prior to prosthetic therapy. This can easily be achieved by the cosmetic dentist in office through the process of adjunctive orchestrated orthodontic therapy, using socially acceptable aesthetic appliances.

Improving implant framework passive fit and accuracy through the use of verification stents and casts.

Passive fit of implant frameworks is related in part to the accuracy of the master cast. A method of fabricating a verification stent to check the accuracy of the master cast prior to waxing and casting the implant framework is discussed. The methods utilize routinely available materials and do not require any special instrumentation or equipment. The stent can be fabricated either by the laboratory or the dentist.

Aesthetic enhancement of anterior dental implants with the use of tapered osteotomes and soft tissue manipulation.

An adequate bone base is usually a prerequisite for functionally and aesthetically optimal reconstruction of the soft tissue architecture around a dental implant. In patients with sufficient bone height but insufficient bone width as a result of tooth loss, a jaw enlargement technique with osteotomes combined with soft tissue manipulation may be utilized to facilitate proper implant placement while concomitantly optimizing the aesthetics of the final implant prosthesis. The learning objective of this article is to familiarize the reader with the principles of ridge expansion with tapered osteotomes combined with periodontal plastic soft tissue surgery to aid in proper implant placement and enhance the aesthetic result of the final prosthesis.

Prosthetic considerations with periodontal root resective therapy, Part 1: Root amputations.

Root resective periodontal therapy is a procedure used to retain teeth needed for restorative abutments or occlusal support. Contraindications of root resective therapy include fused roots and inadequate bony support around remaining roots. When these situations exist, extraction is necessary. But in the appropriate cases, a patient with a periodontal condition resulting in alveolar bone loss in the furcation region is amenable to treatment with a predictable result using a combination of resective periodontal surgical therapy and subsequent timely prosthetic rehabilitation.

Prosthetic considerations with periodontal root resective therapy, Part 2. Hemisections.

When a root and the overlying anatomic crown are removed as a unit, this procedure is referred to as a hemisection. Hemisection of a maxillary or mandibular molar is often a means of retaining teeth needed for restorative abutments or occlusal support. This treatment can yield predictable results using proper diagnostic, endodontic, surgical, and prosthetic techniques.

Aesthetic enhancement of pontic sites for fixed partial dentures.

The ridge expansion technique using tapered osteotomes can be used anywhere in the maxilla when a change in external ridge morphology would be advantageous for both aesthetics and/or proper dental implant placement. Usually subsequent to tooth loss, the maxilla is generally somewhat undercut in form. This ridge expansion technique can be used to reduce the undercut by bulging out the base of the facial/buccal plate. This would recreate the illusion of root prominences (Figure 12) or permit implant fixtures to be inserted in a more upright position. The tapered osteotomes can therefore predictably be used to expand the buccal bone to simulate the presence of a root prominence for optimal aesthetics for placement of a fixed partial denture prosthesis (Figure 13).

Salvaging of adjacent fixed partial dentures using an overcasting technique.

Occasionally, clinicians are faced with a situation in which a solitary tooth between two bridges requires extraction. When this type of situation occurs, we must ponder the dilemma of how to replace the missing tooth. Options include placing an implant where the tooth was extracted or remaking one large multiunit bridge. Implants are not always possible or practical, and remaking a multiunit bridge that involves the abutments of the two existing bridges can be challenging and becomes much more expensive to the patients. The overcasting technique is a treatment modality that offers a solution in these particular situations.

Using cross-sectional tomography to perform exploratory radiography in lieu of exploratory surgery.

Preoperative treatment planning for dental implants is crucial to their integration and especially prosthetic rehabilitation. Exploratory radiography is an essential component of treatment planning. Radiographic examination using cross-sectional tomography as an adjunct to panoramic radiographs can significantly decrease the incidence of exploratory surgery that could result in unplanned bone augmentation procedures due to insufficiency in alveolar bone height, width, quantity, quality, and will not allow proper aesthetic prosthetic rehabilitation subsequent to improper implant placement.

The late development of oral pyogenic granuloma as a complication of pregnancy: a case report.

An oral pyogenic granuloma can develop during or just after the first trimester of pregnancy. Usually, an oral pyogenic granuloma is an early, slow-growing mass that, on excision, does not leave a large defect in the periodontium that requires surgical repair. This article presents an unusual case of a very late, rapidly growing, large tumor that developed as a complication of pregnancy and an undiagnosed isolated area of periodontal disease.
