However, the increased wear is likely to prevent any damage to the more complex and expensive metal-ceramic fixed implant prosthesis. De Van MM. In 2011, he received Honorary Fellowship in the Faculty of Dentistry of the Royal College of Surgeons in Ireland. Ease of Fabrication/RepairSeveral factors affect the maintenance of restorations, including masticatory forces, restorations in the opposing jaw, parafunctional habits, and type of materials used.51 Several studies have concluded that the incidence of remakes, adjustments, and repairs is higher for implant overdentures as compared to implant fixed complete dentures.52,53 However, it is important to note that implant-assisted fixed prostheses are more challenging and expensive to repair than implant overdenturers.23, Keratinized TissueImplant- and mucosa-supported overdentures rely on support from firm and nondisplaceable tissue to overcome dislodging forces applied by high muscle attachments.17 Hence, implant- and mucosa-supported overdentures are not indicated for patients with limited keratinized (attached mucosa) tissue.17 Also, presence of thick keratinized tissue is important for making an aesthetic fixed metal-ceramic implant restoration.16. 35. Penile implants are devices placed inside the penis to allow men with erectile dysfunction (ED) to get an erection. Clin Oral Implants Res. 40. Thickness of palatal masticatory mucosa associated with age. Prosthesis design considerations are suggested for patients with minimal, moderate, and severe resorption of the edentulous maxilla. Esthetic implant prosthesis, Esthetic considerations: Live Surgery: Module 5: May 29: Live Surgery: May 30: Live Surgery . Prosthetic teeth are positioned on/in close approximation to the ridge. In traditional prosthetics, when a tooth is replaced, the abutment teeth are already provided by nature with wide posterior abutments for posterior teeth. Authors; Authors and affiliations; James H. Abjanich; Ira H. Orenstein; Chapter. Dr. Massad is an internationally recognized presenter in the field of removable prosthodontics. 25. 2012;16:80-83. The increased awareness, demand, survival, and success of implants and implant restorations has shifted the options for restoring the edentulous mouth from conventional dentures to implant-assisted prostheses.3-6 Furthermore, numerous research studies demonstrate that restorative approaches involving implants not only improve the denture-bearing foundation, but also improve edentulous patients’ quality of life and confidence.7-14, Implant assisted prostheses can be fabricated with any of the following designs: (1) removable implant-supported overdenture, deriving support from a rigid bar with posterior bar extensions; (2) removable implant- and tissue-supported overdenture, deriving support from a bar with no cantilever extension; (3) removable implant- and tissue-supported overdenture, deriving support from individual attachments; or, (4) implant-supported fixed complete denture (metal-ceramic, zirconia, or metal-acrylic resin prostheses [formerly known as a hybrid prosthesis]).6,15 The type of restoration to be used must be decided in the treatment planning phase, before the placement of any implants.16, A successful treatment plan should be based on clinical and evidence-based treatment planning, considering all the factors that might have an effect on the desired outcome.17 A detailed assessment of the patient’s hygiene history is a factor that can generally be overlooked. Teeth positioned labial to the ridge for aesthetics. Smedberg JI, Lothigius E, Nilner K, et al. Clin Oral Implants Res. 1990;1(4):10-3. Most studies on prosthesis design and retention do not sufficiently consider factors that influence function of prosthesis, including interarch relationship, degree of jaw atrophy, orientation of implant, dentition/prosthesis in the opposing jaw, and type of occluding materials, occlusion and loading. The lip support can be improved by tipping and labially positioning the maxillary anterior teeth, and by adequately contouring the labial flange of the maxillary implant overdenture.
