RU2173114C2 - Method of temporary prosthetics for period of coalescence of root part of intraosseous implant - Google Patents

Abstract

FIELD: medicine, particularly, orthopaedic stomatology; applicable in two-phase operation of intraosseous implantation. SUBSTANCE: method includes making temporary bridge prosthesis and its removal after elapsing of period of coalescence of root part of intraosseous implant. Bridge prosthesis is made in the form of fixed fibrous prosthesis preventing injury to implant and to surrounding gingivas. EFFECT: restoration of aesthetic and functional full-value set of teeth with partial absence of teeth with provided favorable conditions for coalescence of intraosseous dental implant.

Description

 The relevance of the use of dental implants is determined by the fact that, firstly, 20% of the population under 25 have missing teeth, and by the age of 60, the proportion of partial tooth loss approaches 90%. Secondly, the current trend in the development of dentistry is aimed at maintaining healthy teeth, which, in contrast to traditional fixed bridges, requiring grinding of dental tissues, dental implants satisfy.

 The invention relates to medicine, namely to orthopedic dentistry, and can be used during a two-phase operation of intraosseous implantation according to Brenemarck / 1 /.

 The technique of two-phase implantation consists in the initial implantation of the root of the implant into the bone (1 phase) and the subsequent connection of the head (2 phase). The first phase is completed by suturing the postoperative wound. The second phase of the operation is carried out after healing (after 5-6 months). For the period of implant engraftment (indicated 5-6 months), temporary prosthetics is performed with a removable prosthesis.

 As an analogue, a method for using a direct partial removable laminar denture with a rigid acrylic base is proposed. The specified method does not require grinding of adjacent teeth, as when using conventional fixed bridges with support on the crowns, and to a large extent restores the functional and aesthetic optimum before the final prosthesis / 2 /.

 The disadvantages of the method adopted as an analogue are the stimulation of unwanted eruption of the root of the implant (like a growing tooth) when it comes into contact with the basis of a removable denture. Another disadvantage is the inconvenience of using a removable denture: the mobility of a removable denture when chewing (biting) solid or sticky food; changes in phonetics due to the inevitable distortion of the relief of the anterior section of the hard palate; aesthetic disadvantage, especially in the presence of artificial gums; difficulties getting used to a removable denture).

 As a prototype, it is proposed to adopt a method of temporary prosthetics using a partial removable plate prosthesis with a two-layer (soft) acrylic base, where elastic plastic is used as a layer adjacent to the gum, which reduces the stiffness of contact with the gum / 3 /.

 The disadvantages of the method adopted as a prototype is also the eruption of the root of the implant, which contributes to its contact even with a soft lining. Isolation of the base of the removable prosthesis from the projection area of the implant implanted onto the gum causes the formation of an artificial reservoir where food inevitably falls and impairs healing. In addition, problems remain in using the patient with a removable denture in the same way as with the analogue.

 The authors propose a method of temporary prosthetics for the period of implant engraftment, which consists in the manufacture of a fixed adhesive bridge-based prosthesis on a fiber basis (VAMP). VAMP prostheses are currently used as permanent (their service life is limited only by the adhesive strength of the adhesive joint) fixed bridges when replacing included defects in the dentition.

 The aim of the invention is to restore the aesthetic and functional usefulness of the dentition with a partial absence of teeth while providing favorable conditions for the engraftment of the intraosseous dental implant.

 This goal is achieved by the use of a fixed fiber adhesive bridge-prosthesis, fixed on the enamel of the teeth, limiting the defect of the dentition.

 As a reinforcing element for the VAMP frame, FiberSplint ("Polydentia") multi-layer glass tape and GlasSpan ("C1aSrap") harness stockings or Ribbond ("Ribbond") and Connect ("Kerr") polyethylene tapes can be used.

The method is as follows:
1. Before the implant is promptly implanted into the toothless alveolar bone, the proposed fiber AMP is made on a gypsum model of the patient’s dentition obtained from a previously taken impression.

 2. The first stage of the intraosseous implantation operation is carried out, which consists in introducing the root of the implant into the toothless alveolar process with subsequent suturing of the mucosal-periosteal flap.

 3. A day after the patient has completed the first stage of the intraosseous implantation operation, the fiber adhesive bridge is placed and fixed in the oral cavity.

 4. Removal of vAMPA (after 5-6 months) using a crown picker.

 5. Grinding and polishing of supporting teeth with rubber heads followed by fluoride varnish coating.

 Clinical example.

 Patient I., 36 years old, and / b N 18731, turned to the clinic of orthopedic dentistry for the need to replace a missing 1 maxillary incisor lost as a result of an injury.

 After additional examination methods, prosthetics of 1 upper right incisor were planned by means of a two-stage implantation operation.

 Before surgery, an impression was taken from the upper and lower jaws. A VAMP was manufactured with FiberSplint reinforcing fiberglass tape, supported by 2 right incisors and 1 left maxillary incisor.

 After the first stage of the two-phase implantation operation, the vAMP was tested in the oral cavity and fixed on the abutment teeth using the Revolution adhesive light-curing composite. After 6 months, a follow-up examination noted the engraftment of the root of the implant without eruption.

 The patient was knocked down VAMP from the abutment teeth with a Kopp crown pickup; supporting teeth are polished, polished and the second phase of the implantation operation is performed.

The proposed method ensures (at the time of implant root root engraftment) the fullness of chewing (biting) food while the prosthesis is stationary, does not change the pronunciation of sounds, restores acceptable aesthetics, creates conditions for the root part of the implant to be traumatized, does not cause problems with prosthesis adaptation and ensures temporary prosthetics are reversible (preserves enamel of abutment teeth)
