Implant Angulation Rationale

Long Axis The Implant Mean

The labiopalatal position of the implant within the alveolar ridge influences the emergence point of the implant-supported restoration as well as its contagious marginal contours and the profile of the final restoration. Generally, a proper emergence profile is desirable, for both esthetic and hygienic reasons. Therefore, the labial contour of the implant head has to emerge, as do adjacent natural teeth. The labiopalatal position of the implant body within the alveolar ridge depends to a great...

Cadcam High Strength Ceramics

Shade Analysis And Communication

High strength CAD CAM materials are available in various types of ceramic (i.e., alumina and zirconia) to satisfy the strength and esthetic requirements anywhere in the mouth. They possess light transmission qualities greater than that of ceramometal restorations. However, optical properties vary familiarity with these materials is a must as CAD CAM has become increasingly popular and widely accepted among dentists and laboratory technicians alike.

Periimplant Soft Tissue Optimization

Establishing healthy esthetic gingival appearance around dental implant-supported restorations requires a meticulous assessment of any gingival or periodontal defects, and subsequently has the capacity for restoring any existing defect. Esthetic gingival and periodontal defects can be addressed during the preoperative clinical examination of implant candidates. Examples of gingival and periodontal defects or discrepancies prior to implant therapy are plenty, including loss of attachment levels,...

Preservative Interproximal Papilla Incision

When operating in the esthetic zone, especially the maxillary anterior area, a conservative approach that preserves the papillary tissues can be used routinely. The extent to which the trauma to the soft and hard tissues created by the surgical flap influences peri-implant bone loss is not known therefore, it is critical to create a minimally invasive incision design. The interproximal crestal bone has shown importance and statistically significant healing esthetic values to the overall...

Inlay Tissue Grafting

Minor- to moderate-size edentulous alveolar ridge defects can lead to critical esthetic problems when an anterior fixed prosthesis is to be fabricated, particularly with esthetically conscious patients. In the case of alveolar ridge deformity, the standard pontic size and shape will not maintain a normal and harmonious relationship with the underlying environment, so modifications are necessary. The most common causes of alveolar ridge deformities include developmental defects, advanced...

Preserving Biological Soft Tissue Contours

Due to the significant advancements in dental implan-tology, new titanium or ceramic abutments have been developed for esthetic implant restorations. Also, anatomical abutments that replicate tooth morphology have been introduced to create a better emergence profile (Pow and McMillan 2004). This in turn has facilitated impression making and provisional restoration fabrication. Upon the second-stage surgery, conventional healing abutment is installed that is smaller in size, and therefore the...

Morphology and Nomenclature of the Interproximal Papillae

The morphological configurations of the interdental papilla depend on several factors, such as the volume of the underlying osseous support, the proximal surface topography of the adjacent teeth, and the assistance of the Sharpey's fibers. The osseous structure of the interdental papilla is composed of two crests or peaks that run from the labial and lingual sides. The labial crest is slightly higher than the lingual one, with an intervening distance averaging from 2-6 mm. The two crests are...

Procedures for Papilla Reconstruction

Implant Embrasure

Reconstructing the interimplant papilla is one of the most technique-sensitive procedures in dental implan-tology. It requires greater surgical skills and optimal scientific background. The nature of the interimplant papilla (scar tissues) also might compromise an optimal Figure 8.11. The different morphological variations of the papilla osseous structure. Figure 8.12.

Decision Making in Esthetic Implantology Cases

Decision making in dental implantology cases is one of the clinician's delicate activities. The decisions include selecting a particular treatment method, specific surgical protocols, and particular materials, and they can influence the treatment's final outcome. Factors that affect the decisions in any treatment plan involving dental implant therapy are numerous, including time, cultural and ethnic background, physical appearance, age, profession, cost, lifestyle requirements, personality of...

Medical Evaluation

A complete medical and dental history provides insight into the patient's current state of health. Patients are urged to reveal any ongoing or previous medical treatment and or any medications they are taking as well as any influencing habits. This highlights contraindications or important areas of concern for dental implant therapy (Malamed 1995, Sabes et al. 1970). The medical evaluation can also provide useful information on the potential prognosis of implant treatment (Halstead 1982, Misch...

Esthetic Guidelines of Implant Exposure Surgery

Soft Tissue Manipulation Around Implants

Peri-implant soft tissue morphological characters that closely adjoin the implant components are of great value to implant esthetics. The ability of the clinician to modify and enhance soft tissue contours around dental implants at the time of the second-stage surgery can influence the overall restorative result. An excellent second-stage surgery protocol might help to restore missing biological tissue profile and or restore any related soft tissue contours. Therefore, numerous flap designs...

Achieving Soft Tissue Closure in Immediate Implant Therapy

Free Flap Soft Tissue Graft

Complete soft tissue closure on top of dental implants might present a prerequisite for the overall success of dental implant therapy (Lekholm et al. 1993). Submerging dental implants was originally performed to protect the bone-grafting material from the hostile oral environment and to prevent the migration of epithelial tissues along the socket walls. As a consequence, primary soft tissue closure in immediate implant procedures became a standard clinical routine by many authors (Gelb 1993,...
