Štirn, Ela (author), Bohinc, Peter (mentor), Fošnarič, Miha (reviewer)

Uvod: Obraz predstavlja majhen del telesa, vendar je eden izmed glavnih dejavnikov za socialno identiteto in eno glavnih orodij za medosebno komunikacijo. Izguba zob močno vpliva na anatomske in estetske spremembe obraza oz. ustne votline. Namen: Namen diplomskega dela je pregledati obstoječo literaturo o problemu zmanjšane dimenzije okluzije, opisati pomen dviga navpične dimenzije okluzije (VDO) in začasne protetične oskrbe pred cementiranjem končnih zobnih nadomestkov. V rezultatih diplomskega dela je opisan postopek dviga pacientovega ugriza in izdelava silikonskega predložka za izdelavo začasnega provizorija v ordinaciji, z namenom zaščite krnov in estetike ter izdelava začasnih prevlek v laboratoriju, izdelanih s kombinacijo digitalne in analogne tehnologije. Metode dela: V teoretičnem delu je uporabljena deskriptivna metoda. Glavni vir informacij so članki v različnih znanstvenih revijah in strokovne knjige. Za izbiro literature smo uporabili različne knjižnice in bibliografskih baze, kot so Google Učenjak, Web of Science, PubMed. V praktičnem delu smo v laboratoriju izdelali navosek, silikonski predložek in začasne prevleke iz polimetilmetakrilata s subtraktivno metodo (rezkanje). S tem smo prikazali izdelavo začasnih prevlek z analogno in digitalno tehnologijo. Rezultati: Izdelali smo začasne prevleke, prilagojene na povečano navpično dimenzijo okluzije. Postopek temelji na analognih odtisih, digitalnem skeniranju in izdelavi prototipa. Izdelava vključuje tako digitalne kot klasične postopke. Razprava in zaključek: Ob povečanju vertikalne dimenzije okluzije je pomembno spremljati, kako nova višina vpliva na pacientov ugriz, funkcionalnost čeljusti in okluzijske stike. Z začasno prevleko zobozdravnik preizkusi, ali bo sprememba v dimenziji okluzije udobna za pacienta, preden se sprejme končna odločitev o trajnih zobnih nadomestkih.

• Title: The importance of temporary restorations in increasing the vertical dimension of occlusion : diploma work

Abstract

Introduction: The face represents a small part of the body, yet it is one of the main factors of social identity and a key tool for interpersonal communication. The loss of teeth significantly affects anatomical and aesthetic changes in the face and oral cavity. Purpose: The aim of this thesis is to review existing literature on the issue of reduced occlusal dimension, describe the importance of increasing the vertical dimension of occlusion (VDO), and highlight the role of temporary prosthetic restorations before the final cementation of definitive prosthetic solutions. The results of the thesis describe the process of increasing the patient’s bite and the fabrication of a silicone index for the protection of prepared teeth and temporary crowns, created using a combination of digital and analog technologies. Methods: The theoretical part employs a descriptive method. The primary sources of information are articles from various scientific journals and professional books. Literature was selected using different libraries and bibliographic databases such as Google Scholar, Web of Science, and PubMed. In the practical part, we fabricated a wax-up, a silicone index, and temporary crowns made of polymethyl methacrylate using a subtractive method (milling) in a laboratory setting. This demonstrated the fabrication of temporary restorations using both analog and digital technologies. Results: We created temporary crowns adapted to an increased vertical dimension of occlusion. The procedure is based on analog impressions, digital scanning, and prototype fabrication. The manufacturing process incorporates both digital and conventional techniques. Discussion and conclusion: When increasing the vertical dimension of occlusion, it is crucial to monitor how the new height affects the patient’s bite, jaw functionality, and occlusal contacts. The temporary restoration allows the dentist to assess whether the change in occlusal dimension is comfortable for the patient before making a final decision on permanent dental prosthetics.
