Impact of Orthodontic Treatment on Crestal Bone Resorption in Periodontally Compromised Patients: a Case Series
Svrha: Kako se poveÄava broj pacijenata s parodontnom boleÅ”Äu koji se podvrgavaju ortodontskom lijeÄenju (OL-u), a nema izvjeÅ”taja specifiÄno fokusiranog na utjecaj OL-a u sluÄaju pregradnje alveolarne kosti (PAK-a), odluÄili smo se za retrospektivnu studiju. Ispitanici i postupak: Kod dvadeset i Å”estero pacijenata ortodontski je lijeÄeno 445 od 645 zuba. Unutar alveolarne kosti srednja im je visina iznosila 0,47 posto prije OL-a. Rendgensko snimanje i Ļ2-test upotrijebljeni su za procjenu razlike u PAK-u. Rezultati: Nije bilo gubitka zuba. Pokazali smo da (1) OL ne djeluje Å”tetno na potpornu kost lijeÄenog zuba, a s obzirom na to da su srednje vrijednosti resorpcije alveolarne kosti iznosile 0,03 milimetra kod lijeÄenih i 0,26 milimetara kod nelijeÄenih zuba (2), nije bilo statistiÄke razlike u PAK-u izmeÄu lijeÄenih i nelijeÄenih zuba), tako da (3) duljina aktivnog OL-a nije kritiÄni Äimbenik za PAK. ZakljuÄak: OL je kod pacijenata s parodontnom boleÅ”Äu moguÄe obaviti i postiže se dobar uÄinak na PAK.Objective: Since the number of patients with periodontitis undergoing the orthodontic treatment (OT) is increasing and no report specifically focuses on the impact of OT on crestal bone remodeling (CBR), we performed a retrospective study. Materials and Methods: Twenty six patients had OT on 445 over 645 teeth. The mean tooth high inserted into alveolar bone was 0.47% before OT. X-rays and Ļ2 test were used to evaluate differences in CBR. Results: No tooth was lost. We have demonstrated that (1) OT has no adverse effect on bone supporting the treated teeth (since the mean crestal bone resorption was 0.03 mm and 0.26 mm in treated and untreated teeth, respectively) (2) treated and untreated teeth have no statistical difference in CBR, and (3) the length of active OT is not a critical factor on CBR. Conclusion: OT of periodontally compromised patients
can achieve good results on CBR
