Abstract
INTRODUCTION: Irregularities of the teeth and of the jaws can be inborne or aquired. The more pronounced irregularities need orhodontic and surgical treatment. The diagnostic procedures and treatment planning of these patients still present a great challenge, since along the standard methods, which are two-dimensional, there is a fast developing field of three-dimensional methods. Three-dimensional methods have their advantages but still need further evaluation.
GOALS: We would like to show the morphologic characteristics of slovenian children in the period of growth and development by using a non-invasive three-dimensional method. We would like to set standards for the normal face and so enable us to measure the aberrance from the normal facial relations and to follow-up the patients under treatment. The model of a standard slovenian face has not been developed up to now and the methodology is also still being developed abroad. We would like to asses objectively the soft tissue changes of the patients undergoing complicated othodontic and surgical treatment.
METHODS: 30 girls and 30 boys in different development periods (decidous, mixed and permanent dentition) will be included in the study. 80 adolescents (40 males, 40 females), from 19 to 27 years of age, will also be included in the study. 30 Patients undergoing surgery will be included. Their faces will be scanned with a three-dimensional scanning system. Average values of the facial morphology of children and adolescents will be determined and statistically analyzed. The results of the pre- and postoperative scans will be analysed and compared to standard telerentgenogram analysis.
EXPECTED RESULTS The digital image of the face developed in this way will present a new and more objective approach to the diagnostics of the face, for it means improvement from the two-dimensional analysis to the three-dimensional one. The main advantage of the method is its non-invasive character and this is why it is so appropriate for growth and development studies in specific populations and for comparison of facial morphology characteristics of various racial groups as well as for the diagnostic and follow up purposes of surgical patients.
Significance for science
The digital image of the face developed in this way will present a new and more objective approach to the diagnostics of the face, for it means improvement from the two-dimensional analysis to the three-dimensional one. The main advantage of the method is its non-invasive character and this is why it is so appropriate for growth and development studies in specific populations and for comparison of facial morphology characteristics of various racial groups. This system enables accurate and reliable analysis of facial relationships, volumetrical assessment and evaluation of various methods of orthodontic and surgical treatment.
Further, for the first time it has been demonstrated with the use of a non-invasive and objective method that treatment of unilateral posterior crossbite in the primary dentition is needed and it is effective as it creates conditions for normal development of the orofacial region.
Significance for the country
The most important achievement for the Slovenia is the implemenattion of a contemporary, valid and non-invasive mathod for diagnostics of facial morphology and characteristics in the field of dentistry and medicine. At the begining of the project the cammeras were brought form abroad from foreign research department, which was the main drawback regarding time and costs. The purchase of 3-D cameras and the data processing program is the most outstanding accomplishment for the development of Slovenia. At the beginning of our project it was necessary for us to use cameras of foreign professionals, which presented considerable time limitations for our research work and planning new research developments. Our own cameras will allow us to continue the ongoing researches and start new research projects, which will contribute to better knowledge of the orofacial area and more efficient treatment planning. And more efficient treatment planning means above all reduction of health care and health insurance costs which has a great socio-economic importance.
