Keywords: Bone grafts; Guided tissue regeneration; Periodontitis; Biocompatibility and surgery
The bacterial plaque is considered one of the main factors detrimental to the periodontium. This can generate inflammatory processes that will impair the structures of support and protection of the dental element, which can lead to a loss of bone and, over time and intensity of the disease, can lead to tooth loss.
Periodontitis is a chronic and infectious disease that affects the soft and hard periodontal tissues responsible for supporting and sustaining the dental element and may be closely associated with systemic diseases such as diabetes and cardiac problems that can aggravate the existing disease, Periodontitis, as altered glycemic value, and cardiological disorders, due to effects on the immunological and inflammatory mechanisms, which should be treated palliatively in these cases [1,2].
Periodontitis causes loss of bone support, consequently gingival recession having multifactorial reasons . It is characterized clinically as the gingival migration of the amelo-cement margin to the apical direction, causes accumulation of food in the area, increasing the chances of caries, negatively affects aesthetics, and increased hypersensitivity .
During the use of the biomaterials we must take into account its biocompatibility, toxicity, and its carcinogenic or radiative power [5-8]. Biomaterials are used in an attempt to recover lost periodontal tissues.
In order to obtain a positive result, we must evaluate and take into account lesion characteristics such as: depth, width, volume, texture, as well as to analyze the control of etiological factors and clinical skills, in order to conclude the best type of procedure and the best material to be used. In addition, for each case, systemic conditions and patient hygiene should be analyzed in order to achieve treatment success and a good prognosis [6-9]. There is a wide variety of materials to be selected for treatment of bone lesions, based on the choice of the intensity of the bone defect .
The objective of the present study was to report, through the literature review, the use of biomaterials and promising techniques indicated for the treatment of periodontal bone lesions, highlighting the advantages and disadvantages of the use of each material having as main objective, to provide a good prognosis for the patient.
Experimental and clinical studies were included (case reports, retrospective, prospective and randomized trials) with qualitative and / or quantitative analysis. Initially, the key words were determined by searching the DeCS tool (Descriptors in Pubmed, Health Sciences, BIREME base) and later verified and validated by MeSh system (Medical Subject Headings, the US National Library of Medicine) in order to achieve consistent search.
The words were included Bone grafts, guided tissue regeneration, periodontitis, biocompatibility and surgery. The literature search was conducted through online databases: Pubmed, Periodicos.com and Google Scholar. It was stipulated deadline, and the related search covering all available literature on virtual libraries.
Series of articles and eligibility
A total of 70 articles were found involving guided tissue regeneration and surgery. Initially, it was held the exclusion existing title and duplications in accordance with the interest described this work. After this process, the summaries were evaluated and a new exclusion was held. A total of 40 articles were evaluated in full, and 28 were included and discussed in this study.
Literature review and discussion
Periodontal therapies have as their main characteristic, to return the functionality and health of these structures and to form new tissues that were lost during periodontitis [1-3]. Among the most requested characteristics are: Biocompatibility, ease of application providing a safe operative and favorable prognosis [4,7].
In view of the many biomaterials possible to use, all present the purpose of the induction and proliferation of osteoblastic cells at the site of periodontitis, so that bone production increases and corrects the local bone defects, being called as guided tissue regeneration . These materials can be subdivided into osteoinducers, and osteoconductors. Osteoinducers induce the differentiation of undifferentiated mesenchymal cells into osteoblast cells, thereby increasing and stimulating bone formation [9-12]. Osteoconductors through cell proliferation ensure the deposition of new bone tissue at the site.
Biocompatible materials are indicated as having the ability to induce faster bone repair [11-15]. Among the materials most used for the treatment of bone regeneration, we highlight the use of autogenous, homogenous or allogeneic, heterogenous or xenogenous grafts .
Although autogenous are considered the best option because it presents a good biocompatibility and to be osteoinductive, the fact that it requires a second surgical area, makes the use of xenogens and allogene grafts to be highlighted, being a great option for the treatment of guided bone regeneration, Mainly because it does not require a second surgical area, giving the patient a better postoperative period [7,17].
Autogenous grafts are removed from the person receiving the donor material, they have a higher biocompatibility, besides being osteoinductors, osteoconductors and osteogens, but they present more negative characteristics because they require a donor area requiring a second surgery, obtaining donor material Limited, increased cost, recovery time and possibility of inflammation [3,18].
Homogenous or allogeneic grafts are removed from a person and re-implanted in the same species. However, they have different genetic characteristics, increasing the risk of contamination and inflammation, and requiring greater care in the handling and storage of the material [3,18-20].
The heterogenous or xenogenous grafts, is a material removed from one species and reimplanted in another, also obtaining different genetics, has the advantage of not having another surgery in the individual, being possible to find the industrialized material and at low cost, reducing the chances of contamination and inflammation, providing a good prognosis .
The bovine grafts are classified as organic and inorganic; The organic ones have higher concentration of protein rich in type I collagen, since the inorganic one has absence of protein and being rich in hydroxyapatite (Table 1) [3,21,25].

In view of the different biomaterials indicated for the treatment of bone regeneration, we highlight the use of autogenous, homologous or allogeneic grafts and the heterogenous or xenogenic grafts. Although the use of autogenous grafts is considered a good option for this type of treatment mainly because it presents important characteristics such as biocompatibility and osteoinduction, the fact that it requires a second surgical area ends up making the patient's treatment and postoperative difficult, Restricted. Among the materials that present a good option for the treatment of guided tissue regeneration, the use of xenogene or allogene grafts is highlighted. These have the ability to be osteoinductive or osteoconductive in which they are important characteristics to be successful in this type of treatment.

The use of autogenous fibrin, a material rich in platelets, has been shown to be a great option for the treatment of intra-auricular defects in patients with chronic periodontitis. Through the research it was analyzed that autogenous fibrin provided a reduction of probing depth, periodontal insertion level and increased bone filling in patients who were treated with conventional open-flap debridement when compared to the treatment performed in patients with flap debridement Conventional alone. However, although this treatment showed a great clinical and radiographic effectiveness, there should be a long-term follow-up and control by analyzing the clinical effects of this biomaterial .

The use of elastin membranes derived from bovine atrial cartilage has been shown to be a promising material used in bone regeneration therapies. The elastin membrane has a wide biodegradability making it possible to replace the implanted material by neoformate bone, in addition, it provides support for cell proliferation and is capable of generating immune responses that will facilitate tissue regeneration. This biomaterial presents important characteristics such as osteoinduction, osteoconduction and biocompatibility. Its use is more indicated than the other biomaterials of autogenous origin because it does not require a second surgical area, providing a better prognosis for the patient.
