Abstract
Statement of problem
Clinical research has difficulty keeping pace with the rapid evolution of materials,
protocols, and designs of single-unit implant restorations. The clinical design preferences
of prosthodontics for different clinical scenarios are lacking.
Purpose
The purpose of this cross-sectional survey was to determine the current prevalence
of usage of various treatment options and materials for single-unit implant-supported
restorations.
Material and methods
From August to September of 2022, a survey invitation was sent to members of the Pacific
Coast Society for Prosthodontics (PCSP). The survey was hosted online and asked 37
questions related to the materials, protocols, and design preferences for single-unit
implant-supported restorations in various clinical scenarios. The prompts included
the suggestion that answers should be based on preferences for the “ideal” treatment
of a hypothetical patient seeking implant treatment for the replacement of a single
missing tooth.
Results
Of 133 questionnaires sent via email, 35 were returned. The results are presented
with histograms that use color coding as an experience proxy metric. A total of 87%
of respondents was in private practice, and 60% reported having restored more than
1000 single-unit implant restorations. For the replacement of a single maxillary central
incisor under ideal conditions and angulation through the palatal surface, respondents
preferred bone level implants (93%) and screw-retained restorations (80%), with 50%
of those being zirconia with a titanium abutment and 21% being cast metal-ceramic.
For an identical scenario, except that the angulation would be through the facial
surface, respondents preferred the angled screw system (55%) and cemented (41%) restorations.
For the replacement of a single missing mandibular molar under ideal conditions, respondents
preferred bone level implants (79%) and screw-retained restorations (79%), with 70%
of those being zirconia with a titanium abutment and 17% being cast metal-ceramic.
Conclusions
While a wide range of protocols, designs, and materials exist for the replacement
of a single missing tooth, these results provide a snapshot of current single-unit
implant prosthodontic preferences in the Western United States and Canada.
