Introduction: Replacing missing teeth is important because without them it is difficult to
chew and speak clearly. The teeth support the cheeks and lips which in case of missing teeth,
so-called gaps, leads to droopy mouth. In some cases adjacent teeth and antagonists begin to
move into the gap. This affects the ability to bite evenly. Although milk teeth are replaced
by permanent teeth, they are important during childhood for chewing, speaking and
stimulating the growth of the stomatognathic system. Local and systemic factors contribute
to tooth development. Demographic changes in industrialized countries require dentists to
adapt to the growing group of elderly patients, as well as the development of concepts for
dental care in these cases. In general, dental care for the elderly should be based on their
daily life. Oral hygiene at home has improved over the years and professional cleaning of
teeth and dentures has been established. Tooth loss occurs in older age, which means
extensive prosthetic rehabilitation from fixed and removable dental prosthetics to a higher
average age. Teeth can be replaced with provisionals which can be fixed or removable. They
can be fixed on the patient's teeth or on implants. They are immovably cemented to the teeth.
The disadvantage of these is that they are harder to clean and, as a result, poorer hygiene.
Removable partial dentures can provide the patient with aesthetic relief and functionality
before and during the fabrication of the final prosthetic replacement. Different materials and
techniques can be used for its manufacture. Purpose: The purpose of my thesis is to present
the reasons for missing teeth and tooth loss in children and adults, as well as the substitutes
that are used for temporary replacement before the final prosthetic is made. We have
presented the production of an invisible dental appliance with a replacement tooth, to replace
a missing tooth in the intercanine area. Since there are not many sources of literature on this
topic, purpose is also to collect literature related to the products that are manufactured in the
dental laboratory for temporary tooth replacement. Methods: We have used the descriptive
method of work in my diploma work. In the database of diploma works in RUL in the last
ten years no thesis has been written on a similar topic. We have also searched for professional
literature in Slovenian and English on the web portals Google Scholar, PubMed and Science
Direct. COBISS and koferdam.com. In the dental laboratory we have made an invisible
dental appliance with a pontic to replace tooth 12. We have documented the individual stages
of production with the One Plus CE 5G mobile phone camera. We have processed the images
in GIMP. Results: We have made a replacement in the dental laboratory and photographed
the manufacturing process with my phone. Discussion and conclusion: In our diploma
thesis we have presented the age periods of the growth of individual teeth, the abnormalities
that lead to a lack, the choice of colour before making a denture, the reasons for errors in
determining the colour and the way to prevent it when determening the color shade. We have
briefly presented the shapes of teeth and shape statistics in men and women. All this must
be taken into account when choosing acrylic teeth, in case we do not know what shape the
pacient's teeth had been before the loss. We have also listed and briefly described some
temporary substitutes that are made before the final one is made. We have made a provisional
from foil for the production of retention foils, with the addition of an article in the sub-area
of the missing tooth 12.
