Implant facilitated molar uprighting using CAD-CAM technology.

Area of Science:

• Dental Implantology
• Orthodontics
• Prosthodontics

Background:

• Tooth loss leads to mesial drift of adjacent teeth, compromising masticatory function and hindering ideal prosthetic rehabilitation.
• Mesially tilted teeth, particularly mandibular second molars, can encroach on space required for implant-supported crown fabrication with optimal contours.

Purpose of the Study:

• To introduce and evaluate the efficacy of an osseointegrated implant-supported device, the Implant Supported Distalising Piston (ISDP), for uprighting mesially tilted mandibular second molars.
• To assess the potential of the ISDP to facilitate more ideal implant restorations in cases of tooth loss.

Main Methods:

• Utilized CAD-CAM technology to design custom implant-supported zirconia crowns incorporating a distalising piston.
• Applied the ISDP device to upright two mesially tilted mandibular second molars in patients seeking prosthodontic treatment.
• Documented the correction of molar tilt and the subsequent design of implant-supported crowns.

Main Results:

• The Implant Supported Distalising Piston (ISDP) successfully uprighted two mesially tilted mandibular second molars.
• The correction of molar tilt allowed for the fabrication of implant-supported crowns with more ideal contours.
• The device facilitated improved space for prosthetic rehabilitation.

Conclusions:

• The ISDP is an effective osseointegrated implant-supported device for correcting mesially tilted molars.
• This innovative approach enhances the possibilities for ideal implant restorations in complex clinical scenarios.
• The ISDP offers a viable solution for managing space encroachment caused by tooth migration after tooth loss.
