In the edentulous upper jaw the placement of implants can be challenging due to limited bone quantity and the presence of the maxillary sinus. Pterygoid implants have high success rates, similar bone loss levels to those of ...

Implant supported overdentures are an evidence-based treatment option for edentulous patients leading to a significantly increased quality of life.
There are various retention elements available which connect the implants directly...

In the edentulous upper jaw the placement of implants can be challenging due to limited bone quantity and the presence of the maxillary sinus. Pterygoid implants present an alternative option to use residual bone for implant anchorage and to overcome the need for...

Indications

Zygomatic implants have been documented as a an alternative for the rehabilitation of the atrophic posterior maxilla with both the classical two stage and immediate loading protocols. Zygomatic implants avoid grafting and sinus lift procedures and therefore contribut

Less than 4-6 mm of vertical residual bone height in the posterior segment of the maxilla is an indication for a sinus augmentation procedure [Esposito]. The external access to the maxillary sinus is carried out at a lateral buccal alveolar...

The tradition to insert 6 implants, and eventually more, in an arch-wide pattern dates back to the early days of osseointegration when implants with a machined surface were used and risk for early...

A choice of occlusal schemes can be employed for the prosthodontic rehabilitation of the edentulous patient. Clinical outcomes with different schemes continue to be debated and no one scheme has emerged as clearly superior. However, although the...

This is the reversible inflammatory process in the soft tissues around functioning implants. Peri-implant mucositis occurs in almost 60% of subjects (± 30% of sites), restored with implants. Diagnosis is stated by clinical examination: redness, ...

Inflammation can be limited to the soft tissue around the implant (mucositis) or involve the underlying bone tissue as well (peri-implantitis). Infection can be caused by various risk factors, such as inadequate hygiene and patient compliance...

Presence/number of implants influences aerobe and anaerobe species in saliva and on tongue in edentulism. Subgingival microbiota in periimplantitis vary according to studies. Less periodontal pathogens than in partial edentulism. Prevotella nigrescens,...

In the rush to meet patient demands for functional rehabilitation, the importance of occlusion is often overlooked. A check of the occlusion should be performed at every visit from insertion onwards because many problems with fixed dental prostheses can...

Attachment selection

The relative merits of different prosthodontic treatment objectives - resilient versus rigid attachments - are controversial and empirical. A resilient retention mechanism is recommended on the assumption that this will protect implants from overload; while in...

Placement of a removable prosthesis requires attention to detail to cover all important clinical items such prosthesis fit, denture base extensions, esthetics, occlusion, patient comfort and post-insertion instructions. Implant overdentures may or may not...

The patient with a terminal dentition and who faces total teeth extractions can choose from a number of treatment options from immediate complete denture to one of the implant supported protocols.
Immediate dentures are chosen by patients who are unwilling...

Research and clinical experience show that conventional complete dentures are acceptable for a large segment of the edentulous population. Satisfied complete denture wearers are well adapted to their prosthodontic experience and have...
