PROCEDURE FOR PRODUCING IMPLANTS WITH A PERSONALISED SURFACE

Abstract

PROCEDURE FOR PRODUCING IMPLANTS WITH A PERSONALISED SURFACE that involves the cleaning/activation of the implant surface by means of plasma technology using oxygen or argon plasma to obtain surfaces with no organic compounds or oxide layers, and the application of a liquid solution that is designed for each patient and contains a single osteoconductive, osteoinductive, antibiotic, antibacterial or probiotic component, or a combination of any of them. The cleaning/activation of the implant surface by means of plasma technology may be carried out in the clinic or in the implant production plant and the liquid solution may be applied in the dental clinic just before the implant placement procedure.

Description

DETAILED EXPLANATION OF ONE METHOD OF IMPLEMENTATION

[0016] After planning the procedure, in other words, after studying the biology of the patient's jawbone, habits, medical history and analysing the patient's possible surgical trauma, based on the data obtained, the solution (which may be formed by a single osteoinductive, osteoconductive, antibacterial, antibiotic or probiotic compound, or a combination of any of them), is applied to the implant surface in order to increase the BIC (bone implant contact) values.

[0017] To ensure that the liquid penetrates all the micropores of the implant surface, before the implant procedure, the surface is cleaned/activated using plasma technology to obtain a surface with no innate titanium oxide layer in contact with air, making it highly reactive and allowing the corrective/enhancing liquid to penetrate the entire surface of the implant.

[0018] Normally, dental implants are supplied ready sterilised. The dental implant packaging consists of the implant in a vial, which in turn is inserted in a blister pack and hermetically sealed to maintain its sterility.

[0019] Thus, after obtaining the patient's data regarding the type of bone, biology, medical history and habits that could affect the correct osseointegration, the solution is selected with the most appropriate single or combined compound in each case, and it will therefore be an osteoinductive or an osteoconductive compound, an antibiotic or an antibacterial compound or a compound containing a combination of any of the above substances.

[0020] In particular, the types of solution used and their composition and quantity, depending on the different patient pathologies, will preferably be the following: [0021] Probiotic fluid: Promotes the development of non-pathogenic flora. [0022] Quantity of fluid: Vials containing between 2.5 cm.sup.3 and 5 cm.sup.3. [0023] Composition: Fluid comprised mainly of Lactobacillus or similar bacteria. [0024] Patient pathologies: [0025] Osteopenia [0026] Hyperparathyroidism. [0027] Antiobiotic fluid: Promotes the inhibition of collagen and protein synthesis. [0028] Quantity of fluid: Vials containing between 2.5 cm.sup.3 and 5 cm.sup.3. [0029] Composition: Fluid comprised mainly of tetracycline, terramycin or similar drugs. [0030] Patient pathologies: [0031] Decontaminants. [0032] Prevention of periodontal and/or peri-implant disease recurrence. [0033] Immunity problems. [0034] Osteoinductive fluid: Promotes the formation of bone. [0035] Quantity of fluid: Vials containing between 2.5 cm.sup.3 and 5 cm.sup.3. [0036] Composition: Fluid of human origin (patient or donor), mostly made up of stem cells, platelet-derived growth factors or morphogenetic proteins. [0037] Patient pathologies: [0038] Acute osteoporosis. [0039] Chemotherapy or radiation therapy. [0040] Bone mineralisation disorders. [0041] Osteoconductive fluid: Promotes the maintenance of vital space for bone formation. [0042] Quantity of fluid: Vials containing between 2.5 cm.sup.3 and 5 cm.sup.3. [0043] Composition: Fluid consists mainly of hydroxyapatite and tricalcium phosphates. [0044] Patient pathologies: [0045] Tooth extraction and immediately placement of implant. [0046] Cyst cavities (bone defects). [0047] Defects that complicate the healing of bone tissue.

[0048] The implants to be placed in the patient's mouth undergo the plasma cleaning/activation process, which takes no more than 15 minutes, preferably at the time of surgery. For this purpose, the sealed blister must be opened and the vials must be extracted with the implants and placed in the plasma machine.

[0049] This plasma cleaning process has different phases. Firstly, the UV light generated in the plasma breaks up and lifts off most of the organic adhesives and surface contaminants. The particles dragged from the surface react chemically with the plasma oxygen ions, producing other molecules such as water and carbon dioxide, which are removed from the chamber by the vacuum system. In the plasmas generated for cleaning oxidable metals in which there is no oxygen, the particles removed from the surface are removed outside the chamber to prevent the re-depositing of material, leaving the surface ultra clean and ready for adherence.

[0050] Once the programmed cycle has ended, the vials are extracted with the implants inside them and the vial cap is removed. Without extracting the implants from the vial, the programmed sterile fluid is poured into the vial to reduce possible defects and/or enhance the patient's biological virtues and increase in the BIC values, thus improving the osseointegration of the implant in the patient's bone.

[0051] Then the implants are placed in the patient in the normal way.

[0052] Having described in sufficient detail the nature of this invention and the way in which it is put into practice, it is not considered necessary to make a more extensive description to allow an expert in the matter to understand its scope and the benefits it brings. It is stated that, within its essential design, it may be put into practice through other methods of implementation that differ in detail from what is indicated by way of example, with such methods being included within the scope of protection sought, provided the fundamental principle is not altered.
