Is Cone-Beam Computed Tomography (CBCT) Effective in Arch Discrepancy Measurement? A Comparative Study Using a Digital Program
Beatriz Tarazona*, Pablo Tarazona-Álvarez, Rosa Cibrián, José Luis Gandía, Vanessa Paredes
Arch discrepancy measurement is one of the most important calculations when it comes to devising a correct diagnosis and treatment plan. Any small millimetric difference can be crucial in deciding on one treatment or another, with or without extractions.
Literature Review: Partially Denture Arches Main Classifications
Jefferson Ricardo Pereira* – DDS, MSc, PhD. , Edem Jhon Volpato – DDS., Mateus Carlos Gonçalves Feltrin – DDS., Dimas João Rodrigues Neto – DDS, MSc, PhD Student (PUC/RS)., Saulo Pamato – DDS., João Paulo De Carli – DDS, MSc
Several classifications for the partially denture arches have been proposed since the begining of the past century; however they are still used to date. This literature review revealed an antithesis among authors due to various parameters involved in the attempt to include all the requirements of a classification. With regards to variations between mechanical and topographic aspects, the position of retainers remains rather confusing. In order to improve the understanding of such matter, an analysis of all aspects relating to the main classifications was carried out.
Sequential Theory of Impaction of Permanent Maxillary Canines–Culmination of Guidance Theory and Genetic Theory
Anand K. Sajnani BDS, PGDMLS, MDS (Hons)
The location of the permanent maxillary canine at the angle of the mouth is strategically significant in maintaining the harmony and symmetry of the occlusal relationship and in determining the contours of the oral cavity. However, the maxillary canine is the second most frequently impacted tooth with the prevalence of impaction reported to be between 1-2% in the general population. Moreover, treatment of this condition is often complex and involves substantial time and financial cost. Hence, it is only prudent to monitor the eruption patterns and identify the aetiological factors that lead to impaction of the maxillary canine.
