Plasma rich in growth factors scaffold showed no advantage over blood clots regarding healing of the periapical radiolucency, radiographic apical closure and type of the newly formed soft and hard tissues.
Objectives:
To compare archwire selection on dental casts with archwire selection using a three-dimensional (3D) software program (OrthoAid) and assess agreement between clinicians.
Materials and Methods:
The best-fitting archwires were selected for dental casts of 100 patients with malocclusion using two approaches by three orthodontists. The first method was to visually determine the fitness of five preformed nickel titanium archwires to the arch form on a dental cast (subjective method). The second method was archwire selection on a virtual image of the same cast by means of 3D software (objective method). Agreement between selections performed by the orthodontists was calculated using Kappa statistics. The accuracy of fit of the archwires to the curves fitted to the arch form was also calculated or reversely assessed by means of the root mean square (RMS) for both methods using the Dahlberg formula.
Results:
The mean RMS of the distances between the patient arch forms and the archwires for the subjective method was 1.163–1.366 mm. The agreement of selections between orthodontists was 42%–58% (Kappa ranged from .074 to .382). Using the 3D software (objective method), the mean RMS decreased to 0.966–1.171 mm, and agreement increased to 47% to 84% (Kappa ranged from .444 to .747).
Conclusions:
The use of 3D computer software for archwire selection in patients with malocclusion provided better adaptation and interexaminer reliability.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
