RU2432924C1 - Method of temporary prosthetics with non-removable dental bridges - Google Patents

Abstract

FIELD: medicine.

SUBSTANCE: invention relates to field of medicine, namely to orthopedic dentistry. Two-stage dental implants are installed. In spaces between two-stage implants, in area of formation of gingival papillae, temporary implants are installed. Monolithic temporary prosthesis is made from composite material, containing a group of artificial teeth, which compensate dentition defect, taking into account location of location of support heads of temporary implants inside contact surfaces of temporary prosthesis. In place of adjoining mucosa of prosthesis bed to temporary dental bridge formed are dome-shaped roundings in form of gingival papilla, with 1 mm clearance between gum and prosthesis.

EFFECT: method makes it possible to form, in period of osteointegration of dental implants, red esthetic line with expressed gingival papillae and due to location of temporary support implants inside contact surfaces of temporary dental bridge, producing gum massage, which stimulates its growth, and dome-shaped roundings, providing spaces for said growth.

Description

The invention relates to medicine, in particular to orthopedic dentistry, and can be used for prosthetics with temporary bridges during the osseointegration of dental implants.

Temporary crowns are used to restore chewing function for the period of manufacture of permanent crowns or bridges, as well as for two-stage dental implantation for the period of osseointegration.

A temporary bridge is known (Tournal of Prosthetic Dantistry, Sept. 1989, Vol.62, N3, p.16A).

Known temporary denture (Switzerland, patent No. 675354, publ. 90.09.28, No. 18), which is made of soft synthetic material. Such a prosthesis facilitates hygiene and supports the patient's psyche.

Known temporary denture (RF Patent No. 2063192 of 07/10/1996), adopted as a prototype. This prosthesis, which is supported by the implant and contains a removable bridge-like part, has a base with locks and an opening for the implant, the base being made of three layers of rigid plastic, elastic plastic and a layer of medicinal material. This design allows to improve the process of bone tissue regeneration after the implant implantation operation, as well as to evenly distribute the chewing load on the implant, which improves its fixation in the bone.

However, this prosthesis is difficult to manufacture and does not optimize the soft tissues of the mucous membrane of the prosthetic bed before permanent prosthetics with fixed dentures based on the implant.

The problem to which the invention is directed is to temporarily restore the patient's masticatory function, who is shown prosthetics with fixed dentures with support on implants, as well as optimization of the soft tissues of the mucous membrane of the prosthetic bed before permanent prosthetics with fixed dentures.

The technical result of the invention is the formation during the period of osseointegration of dental implants of a red aesthetic line with pronounced gingival papillae with a cervical line that aesthetically satisfies the patient, and improving the conditions for the implementation of hygiene measures of the prosthesis.

The technical result is achieved due to the fact that the method of temporary prosthetics with fixed bridges is to manufacture a temporary prosthesis from a composite material made in one piece, containing a group of artificial teeth, supporting on temporary implants and compensating for a defect in the dentition located in the projection of the installed two-stage dental implants, made in such a way that temporary support implants are located inside the contact surfaces of the temporary bridge and Foot prosthesis, in which the surface in place prosthetic bed adjacent to the mucosa are domed shaped fillets of the gingival papilla, some distance away 1 mm.

The invention is illustrated in the drawing, which shows:

1 - gingival papilla;

2 - dome-shaped fillets of approximate surfaces;

3 - a gap between the mucous membrane of the regional periodontal (gum) and the prosthesis;

4 - artificial tooth;

5 - two-stage dental implant;

6 - temporary implant;

7 - bone tissue.

The method of temporary prosthetics with fixed bridges is as follows.

1. Clinical examination of the patient and obtaining diagnostic impressions from both jaws and a silicone registrar of tooth relationships in central occlusion.

2. Installation of two-stage dental implants.

3. Installation of temporary implants.

4. Production of diagnostic plaster models of the jaws and their fixation in the articulator.

5. The study of plaster models, the inclination of temporary implants, limiting the defects of the dentition, their length, especially the occlusal relationship of the dentition in the articulator.

6. Production of a temporary prosthesis on the obtained model from wax with the formation of dome-shaped roundings of approximate surfaces.

7. Substitution of wax on the composite.

8. Processing, grinding and polishing of the obtained prosthesis.

9. Fitment and fixation of a temporary denture in the oral cavity based on temporary implants.

Claims (1)

A method of temporary prosthetics with fixed bridges is the manufacture of a temporary prosthesis from a composite material made in one piece, containing a group of artificial teeth supporting on temporary implants and compensating for a dentition defect located in the projection of installed two-stage dental implants, made in such a way that temporary supporting implants located inside the contact surfaces of the temporary bridge, in the surface of which in place adjacent to the mucous membrane of the prosthetic bed there are dome-shaped fillets in the form of a gingival papilla, departing from it by 1 mm.
