Implant supported posterior restorations

Considerations for fabrication of implant- supported posterior restorations Chiche et al 1991 Implant supported prosthesis are a excellent alternative for patients who are reluctant to use RPDs. Implant restorations may be either screw retained or cemented. Cemented prosthesis offer simplicity and good control of morphology but can be considered if removal or no re-servicing is

Guided bone regeneration

Guided bone regeneration at oral implant sites Hämmerle et al 1998 This paper discusses the scientific and clinical aspects of guided bone regeneration (GBR). GBR uses the principles of guided tissue regeneration (GTR), the separation of soft tissue from bone by barrier membranes, to generate bone. Nyman and Karring (early 1980s) developed the method of

Width of Keratinized Gingiva and Gingival Health   

The Relationship Between the Width of Keratinized Gingiva and Gingival Health Lang 1972 The keratinized gingiva includes the free and the attached gingiva and extends from the gingival margin to the mucogingival junction. It is generally believed that an adequate width of keratinized gingiva is important for maintaining gingival health. The facial keratinized gingiva was

Immediate versus delayed loading of dental implants

Immediate versus delayed loading of strategic mini dental implants for the stabilization of partial removable dental prostheses: a patient cluster randomized, parallel-group 3-year trial Mundt et al 2016 long-term survival data for mini implants are lacking and acceptable short-term survival rates (>90 %) of mini-implants are only documented for mandibular overdentures   The short-term survival

Clinical Behavior of fiber Posts

Francesca et al 2003 Clinical Behavior of Translucent-Fiber Posts: A 2-Year Prospective Study Monticelli et al 2003 Fiber posts have overcome some of the limitations of metallic posts (platinum, alloys, or titanium) concerning the esthetic appearance, mode of failure, and clinical performance Carbon-fiber posts for anterior roots meant to provide support to an all-ceramic coronal

Peri-implant soft tissue phenotype modification

Peri-implant soft tissue phenotype modification and its impact on peri-implant health: A systematic review and network meta-analysis Tavelli et al 2020 A review on clinical studies that involved soft tissue augmentation around dental implants and reported findings on KMW, MT, and/or STH changes. Insufficient amount of keratinized mucosa width (KMW) < 2mm around dental implants

Zirconia frameworks for posterior fixed partial dentures

Five-year clinical results of zirconia frameworks for posterior fixed partial dentures Sailer et al 2007 Studies using finite-element analysis demonstrated that during occlusal loading the highest stress within FPDs was located at the gingival side of the connector area. Zirconia exhibits the highest bending strength (900 MPa) and  fracture toughness (9 MPa m1/2 ) of

Assessment of implant stability

Assessment of implant stability as a prognostic determinant Meredith 1998 Clinicians have reported success rates for implants as high as 90%. Endosseous Implants Osseointegration has been defined as “a process whereby a clinically asymptomatic rigid fixation of alloplastic materials is achieved and maintained in bone during functional loading.” Implant survival and implant success are quite

Topographic Implant Surface

Oral Implant Surfaces: Part 1—Review Focusing on Topographic and Chemical Properties of Different Surfaces and In Vivo Responses to them Albrektsson et al 2004 Morra et al  found that machined implants display a lower concentration of titanium on the surface and a higher concentration of carbon than sandblasted, acid- etched, or plasma-sprayed surfaces. Wear is

Gingival displacement

Current concepts in gingival displacement Donovan et al 2004 This article discusses the concepts of gingival displacement for optimal impressions Inadequate impressions are frequently forwarded to commercial laboratories, and the chief deficiency seen in such impressions is inadequate recording of the cervical finish lines.  The primary reason for not adequately capturing marginal detail is deficient
