Influence of the maxillary third molars and the surrounding cortical plate during maxillary tooth movement with TADS- A CBCT Study.
Objective: To determine the influence of the presence/absence of third molars and intact/loss of cortical plate of the maxillary tuberosity on the amount of distal movement of the maxillary first permanent molar during distal movement of the maxillary dentition with mini-implants.
Materials and methods: Thirty six maxillary tuberosity sites were evaluated in eighteen young adult patients. The distal movement of the entire maxillary dentition was performed with mini-implants with 200 g of distalising force applied from the mini-implant placed in the maxillary posterior buccal region to attachments placed on the arch wire between the maxillary lateral incisor and canine bilaterally. The distal movement of the maxillary first permanent molars was measured on lateral cephalograms. The maxillary tuberosity sites with intact cortical plate due to congenitally missing third molars or atraumatic extraction of third molars (G1), partial loss of cortical plate due to surgical removal of third molars (G2), fully erupted third molars (G4), third molars located at (G3), and below the cementoenamel junction (G5) were evaluated with cone beam computed tomography. One way Anova and Fisher LSD test was done.
Results: The order of greater to lesser amount of distal movement of the maxillary first permanent molar depending on the integrity of maxillary of tuberosity was partial loss of cortical plate, third molars at the cementoenamel junction, third molars below the cementoenamel junction, intact cortical plate and fully erupted third molars.
Conclusion: The integrity of the cortical plate and the relative position of the maxillary third molar to the second molar influence the amount of distal movement of the maxillary first permanent molar during distal movement of the maxillary teeth with TADS.
Clinical relevance: The amount of distal movement of the maxillary dentition appears to depend on the presence or absence of the third molars and the condition of the cortical plate in the region of the maxillary tuberosity and thereby greatly influence the outcome of treatment.
期刊介绍：
Oral & Maxillofacial Surgery founded as Mund-, Kiefer- und Gesichtschirurgie is a peer-reviewed online journal. It is designed for clinicians as well as researchers.The quarterly journal offers comprehensive coverage of new techniques, important developments and innovative ideas in oral and maxillofacial surgery and interdisciplinary aspects of cranial, facial and oral diseases and their management. The journal publishes papers of the highest scientific merit and widest possible scope on work in oral and maxillofacial surgery as well as supporting specialties. Practice-oriented articles help improve the methods used in oral and maxillofacial surgery.Every aspect of oral and maxillofacial surgery is fully covered through a range of invited review articles, clinical and research articles, technical notes, abstracts, and case reports. Specific topics are: aesthetic facial surgery, clinical pathology, computer-assisted surgery, congenital and craniofacial deformities, dentoalveolar surgery, head and neck oncology, implant dentistry, oral medicine, orthognathic surgery, reconstructive surgery, skull base surgery, TMJ and trauma.Time-limited reviewing and electronic processing allow to publish articles as fast as possible. Accepted articles are rapidly accessible online.Clinical studies submitted for publication have to include a declaration that they have been approved by an ethical committee according to the World Medical Association Declaration of Helsinki 1964 (last amendment during the 52nd World Medical Association General Assembly, Edinburgh, Scotland, October 2000). Experimental animal studies have to be carried out according to the principles of laboratory animal care (NIH publication No 86-23, revised 1985).
