Long-term aesthetic and functional equivalence of implant-supported crowns in lateral incisor and canine positions

Implant-supported crowns in lateral incisor and canine positions demonstrate comparable long-term aesthetic and functional outcomes for patients.

Clinical Oral Investigations · 2023

Key Findings

01Patients reported equal satisfaction with crown shape and color in both positions at baseline and long-term.
02No differences in TMD outcomes were reported or observed clinically.
03Implant-supported crowns in canine positions showed increased bleeding on probing and greater pocket depth at long-term follow-up compared to lateral incisor positions.
04Initial discrepancies in crown color grading (too dark for lateral, too light for canine) were resolved by long-term follow-up, with no significant differences in crown color, gingiva color, or papilla appearance between groups.

Application

Design takeaway

How to apply

When designing or selecting implant-supported crowns, consider the long-term maintenance requirements and potential for periodontal complications, especially in areas with higher biomechanical stress or different gingival biotypes.

Project actions

01When researching dental prosthetics, consider both immediate user satisfaction and long-term durability.
02Investigate the impact of material choices on both aesthetics and biological responses over time.

Method & Evidence

AimTo evaluate the long-term aesthetic and functional performance of implant-supported crowns in maxillary lateral incisor and canine positions.

MethodProspective cohort study with long-term follow-up.

ProcedureThirty-two patients with implant-supported crowns in lateral incisor or canine positions were assessed at baseline and after a mean of 11.1 years. Assessments included patient-reported outcome measures (PROMs) for aesthetics and function, and clinical examinations of crown color, gingival color, papilla appearance, periodontal health, and temporomandibular disorder (TMD) outcomes.

Sample32 participants at baseline, 24 at long-term follow-up.

ContextRestorative dentistry, implantology.

Variables

IV["Position of implant-supported crown (lateral incisor vs. canine)"]

DV["Aesthetic outcomes (crown shape, crown color, gingiva color, papilla appearance)","Functional outcomes (patient satisfaction, TMD outcomes)","Periodontal health (bleeding on probing, pocket depth)"]

CV["Patient demographics (age, sex)","Time since implant placement (baseline vs. long-term follow-up)"]

Strengths & Limitations

Strengths

+Prospective cohort design allows for tracking changes over time.
+Inclusion of both patient-reported outcomes and clinical examinations provides a comprehensive assessment.

Limitations

The study is specific to dental implants and may not apply to other types of prosthetic designs. The long-term follow-up period is significant but still represents a segment of a product's potential lifespan.

Reliability & validity

The study's reliability is supported by standardized clinical assessments and statistical analysis. Validity is enhanced by using validated PROMs and a prospective design, though potential biases in patient selection or recall could exist.

Think critically

How might the initial design choices (e.g., material, abutment type) influence the long-term periodontal health observed around implant-supported crowns?

Design Principles

"Long-term functional and aesthetic equivalence in restorative design can be achieved through careful material selection and placement, with potential site-specific considerations for maintenance."

This research provides valuable insights into the longevity and user satisfaction of dental prosthetics, informing design choices for restorative dentistry. Understanding the long-term performance of different implant crown positions can guide material selection and aesthetic considerations to ensure patient well-being and functional restoration.

What This Means for Your Design

Dental crowns on implants in the front of your mouth (like canines and side teeth) look and work just as well over many years, but the gum health around the canine implants might need a bit more attention.

How to use in your project

1.Reference this study when discussing the long-term viability and user acceptance of restorative dental designs.
2.Use the findings to justify design choices related to material selection and aesthetic considerations in your design project.

Paragraph starter

This research indicates that implant-supported crowns in maxillary lateral incisor and canine positions exhibit comparable long-term aesthetic and functional outcomes, with patients reporting sustained satisfaction. While both positions are functionally equivalent, the canine positions showed a greater tendency for periodontal issues, suggesting a need for careful design and maintenance considerations to ensure overall oral health.
