A novel method for volumetric assessment of tooth wear using three-dimensional reverse-engineering technology: A preliminary report

Abstract

Regional registration of teeth in 3D digital models is useful for quantitative evaluation of tooth wear in orthodontic patients. This method may also be used to assess treatment results in restorative dentistry.

Quantitative comparison of incisal tooth wear in patients receiving one-phase or two-phase treatment for skeletal Class III malocclusion with anterior crossbite

“…8 In contrast, no significant gender difference (Table 2) and no significant correlations between tooth wear during orthodontic treatment and age, ANB angle, FMA, or treatment duration were observed in the present study (Table 4). The results were consistent with previous results 13 that showed no significant correlation between canine wear during orthodontic treatment and age, gender, treatment duration, or craniofacial morphology. The amount of tooth wear during orthodontic treatment may depend on the orthodontic treatment methods and therefore may not follow the natural tooth wear pattern.…”

“…3D superimposition is used widely to evaluate orthodontic tooth movement, [22][23][24] but few studies 13 have investigated tooth wear caused by orthodontic treatment using this method. In the present study, the method previously developed for canines, in which the mesial and distal boundary planes were designated 1.5 mm from the corresponding contact points, was modified 13 These planes were designated 0.5 mm from the contact points in the present study to include the largest possible portions of the incisal edges. In future research, individual boundary planes should be defined based on tooth shape.…”

“…6,7,11,12 Tooth wear may occur during orthodontic treatment as a result of occlusal interference and abrasion by orthodontic appliances. A few studies have investigated tooth wear occurring during 13 and after orthodontic treatment. 3,14 However, no report has described tooth wear occurring during the treatment of anterior crossbite, although the incisors play important roles in occlusal function and dental esthetics.…”

“…Cha et al 19 and Park et al 13 have shown that the volume of tooth wear in orthodontic patients can be measured by the superimposition of three-dimensional (3D) digital models. Park et al 13 introduced a 3D digital superimposition method for the quantitative evaluation of canine wear during orthodontic treatment; this study was the first to calculate tooth wear volumetrically using 3D reverse-engineering technology. In the present study, incisal tooth wear occurring during early and late (camouflage) interventions for skeletal Class III malocclusion with anterior crossbite was evaluated quantitatively.…”

Comparative Analysis of Two Methods of Assessment Wear of Dental Materials

“…To determine the usefulness of the applied method, we use specific statistical procedures to analyze the obtained information on dental materials. There are measurements of volumetric loss of dental materials making use of such methods as 3D digital scanning of dental casts (Park et al, 2014), confocal microscope, profilographometer (Paepegaey et al, 2013) and another.…”
