Orthodontic space closure versus implant placement in subjects with missing teeth

Area of Science:

• Orthodontics
• Dental Implantology
• Periodontology

Background:

• Missing teeth in young adults present treatment challenges.
• Orthodontic space closure and dental implants are primary alternatives.
• Evidence-based decision-making requires a comprehensive review of existing literature.

Purpose of the Study:

• To systematically review and compare orthodontic space closure and implant placement for missing teeth in young adults.
• To identify the advantages and disadvantages of each treatment modality.
• To highlight factors influencing treatment choice.

Main Methods:

• A systematic literature search was conducted in the MEDLINE (PubMed) database from 1990 to 2007.
• Inclusion criteria focused on English language or English abstract studies, yielding 91 articles.
• Only 11 relevant articles, including prospective, retrospective, review papers, and case reports, were accepted after exclusion of less relevant studies.

Main Results:

• Both orthodontic space closure and implant placement offer distinct advantages and disadvantages.
• Treatment decisions are significantly influenced by knowledge of tissue reactions to orthodontic space closure.
• Understanding dentofacial development, including ongoing changes in dentition and supporting tissues, is crucial.

Conclusions:

• A balanced consideration of pros and cons for both space closure and implant placement is necessary.
• Further basic science research and large-scale clinical follow-up studies are essential.
• Informed treatment planning requires integrating knowledge of tissue response and developmental factors.
