Abutment selection in implant-supported fixed prosthodontics.

Area of Science:

• Dentistry
• Biomaterials Science
• Prosthodontics

Background:

• The selection of dental implant abutments is often complicated by the wide array of available options, including numerous implant types and transepithelial abutments.
• Many restorative dentists opt for fabricating custom abutments due to the perceived complexity, despite the higher costs associated with them.

Observation:

• Prefabricated abutments are generally preferred over custom ones, except in specific clinical scenarios.
• Key criteria for selecting the correct abutment include implant position, angulation, soft tissue height, and available interocclusal space.
• The article reviews recent advancements in implant abutment technology and introduces an indirect laboratory-based method for abutment selection.

Findings:

• A systematic methodology is presented for choosing the most suitable abutment in various clinical situations.
• The review covers the latest modifications and developments in implant abutment design and materials.
• An indirect, laboratory-based approach to abutment selection is detailed.

Implications:

• Implementing a systematic selection process can lead to more predictable and cost-effective restorative outcomes.
• Understanding the criteria for selecting prefabricated abutments can help dentists avoid unnecessary fabrication of custom abutments.
• The reviewed advancements and indirect selection method offer practical solutions for clinicians facing complex implant restorative cases.
