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.

Dental Implantation, Endosseous↗

The microbiota of the peri-implant region in health and disease.

The subgingival microflora associated with dental implants has been shown to be similar to that associated with natural teeth. Like the natural tooth, a dental implant may be susceptible to a plaque-induced gingivitis which may progress to peri-implantitis. A similarity exists between the microbial flora around failing implants and organisms classically associated with periodontal disease. The same anaerobic gram-negative organisms are found in periodontitis and peri-implantitis. The periodontium must be in a healthy state before the placement of dental implants and constantly monitored while implants are in function for early detection of potential periodontal and/or prosthodontic problems. The relationship between the microbial flora around dental implants and peri-implantitis is discussed and recommendations are presented to improve the efficacy of dental implants.

Connective tissue grafting for improved implant esthetics: clinical technique.

The subepithelial connective tissue graft can be used to enhance the esthetic appearance and gingival contour of the peri-implant tissues. A technique is described and illustrated to create a soft-tissue root prominence and mask the grayish color that may be present as a result of a thin facial alveolar bony plate and/or thin labial attached gingival tissue over dental implants.

Linear tomography in conjunction with pantomography in the assessment of dental implant recipient sites.

Tomography provides a three-dimensional unobstructed and anatomically accurate picture of the region being viewed. Tomography is a radiographic technique in which a "slice" or section of a given internal body structure is imaged in a pre-determined plane. The advantage of utilizing a tomographic evaluation along with a pantomographic survey is that the clinician may examine the exact position or depth in all three planes of visualization. This radiographic modality can also reveal the quality and quantity of alveolar bone in a pre-determined implant site. This information would allow the clinician better to diagnose, plan treatment, and place dental implants more precisely. Therefore, the utilization of laminar or computerized tomography along with pantomography for more precise visualization and accurate measurement of available alveolar bone of the buccal-lingual and labial-palatal perspective will be discussed and illustrated.
