Summary
Improper use of wedges in dental restorations can cause iatrogenic periodontal pathology. Correct wedge selection and positioning are crucial for preventing these issues and ensuring proper restoration contour and contact.
Area of Science:
- Dentistry
- Periodontology
- Restorative Dentistry
Background:
- Overhanging margins of proximal restorations are a significant iatrogenic cause of periodontal pathology.
- The high incidence of these issues necessitates greater attention from the dental community.
Purpose of the Study:
- To highlight the role of wedges in restorative procedures and their impact on periodontal health.
- To emphasize the prevention of iatrogenic periodontal pathology linked to restorative techniques.
Main Methods:
- Review of variables associated with wedge selection and positioning in restorative dentistry.
- Analysis of common iatrogenic problems arising from wedge misuse.
Main Results:
- Overhanging margins are only one aspect of iatrogenic problems caused by incorrect wedge use.
- Other issues include poor proximal contouring, inadequate contacts, and material under/overfilling.
Conclusions:
- Correct wedge application is essential for achieving matrix band occlusion to the gingival cavosurface line angle.
- Wedge effects on proximal contour and contact require careful re-evaluation before material insertion.
- Availability of various wedge types and carving instruments is vital for optimal outcomes.
