Introduction. In order to achieve the goals of oral implantology, it is of great importance to obtain tissue integration (bone and epithelial) of dental implants. Bone integration has the role of rigidly fixing the dental implant at the level of the supporting bone, while ensuring the transfer of masticatory forces to the neighboring bone, while the soft tissues integration has the role of creating a barrier around these medical devices, with the role of protecting the underlying bone and preventing the access of microorganisms. Purpose. In this material we wanted to perform a statistical analysis on the gingival integration and osseointegration of dental implants in the oral cavity. Material and method. The analysis was performed on a number of 21 patients with a total of 97 dental implants, approximately one year after the prosthetic loading of the implants. The analysis was based on bleeding index, gingival index but also on the depth of the peri-implant canal and bone resorption around the implant. Results and discussions. Most of the implants analyzed showed no signs of inflammation. A small number (less than 30%) showed incipient signs of inflammation, falling within the data in the literature. Conclusions. Early detection of tissue changes around the implant and proper treatment will reduce the risk of more serious injuries and implant failure.

In recent years Titanium (Ti) has been the metal of choice for use as a dental implant material. Vitallium (Vi, and alloy composed of Co, Cr, Ni, and Fe) was considered in the past as an ideal implant material, but current studies show Ti is perhaps better tolerated by tissues in the oral cavity. The purpose of this study is to evaluate the surfaces of Ti and Vi endodontic endosseous implants (EEI) placed in a primate model for one year. In human clinical situations this type of dental implant is sometimes used to stabilize compromised teeth. Under intravenous general anestheisia four cynomolgus monkeys had root canal instrumentation in all central incisors. Placement of the EEI followed a pulpectomy and hand drilling to the proper depth and size for the solid rods to use the bore as a pathway to supporting bone. A total of eight Ti and eight Vi, tapered, size 50, EEI were cleanned, sterilized, and cut to length. Two EEI were inserted in the maxillary (Mx) incisors and two in the mandibular (Md) incisors of each animal. One year after placement animals were perfused via carotid cannulation with an aldehyde fixative. The jaws were retrieved, decalcified, EEI separated from tissue, and processed for scanning electron microscopy (SEM). These experimental EEI samples were critical point dried, mounted on stubs, coated with gold palladium, examined, and photographed with an Amray 1820D SEM. Non-operative control EEI samples were treated, processed the same as the experimentals and photographed with a JEOL JSM 35C SEM. Evaluation of the SEM photomicrographs suggest surfaces of EEI change during: 1) handling to implantation, 2) one year in vivo, and 3) processing. Nonoperative Ti control surfaces (Figs. 1 & 2) appear smooth with crater-like concavities of many sizes, subtle valleying, and crisscrossing machine mark (arrow) [Angle measurements of the crisscross marks compared to the long axis were significantly near 40° for both Ti experimental & control]; Vi control surfaces (Figs. 3 & 4) appear rougher with crevasse-like pits and a machine mark (arrow). Md Ti EEI (Fig. 5) has a prominent insertion gouge (⋆), smoother edged concavities than the control, and pre-operative machine marks like those in Fig. 1 (arrow). Mx Vi EEI surface (Fig. 6) has rounder edged pits and a right side smooth surface blemish (⋆). In conclusion these data suggest that Ti EEI surfaces change less than Vi counterparts. This gathering of information is being correlated with concurrent tissue studies indicating Ti may be better tolerated than Vi EEI which supports the premise that Ti is the material of choice for some dental implants in the tissues of the oral cavity.

Peripheral Ameloblastoma (PA) is the rarest variant of ameloblastoma. It differs from the other subtypes of ameloblastoma in its localization: it arises in the soft tissues of the oral cavity coating the tooth bearing bones. Generally, it manifests nonaggressive behavior and it can be treated with complete removal by local conservative excision. In this study we report a case of PA of the maxilla in a 78-year-old female patient and we describe the four different histopathological patterns revealed by histological examination. After local excision and diagnosis, we planned a long term follow-up: in one year no recurrence had been reported. The choice of treatment is illustrated in Discussion.

Tissue Integration

Successful dental implants rely on stable osseointegration and soft-tissue integration. Titania nanotubes (TNTs) with a diameter of 100 nm could increase the mesenchymal stem cell response and simultaneously decrease Staphylococcus aureus adhesion. However, the interactions between the modified surface and surrounding soft tissues are still unknown. In the present study, we fully investigated the biological behavior of human gingival fibroblasts (HGFs) and the adhesion of Porphyromonas gingivalis (P. gingivalis). TNTs were synthesized on titanium (Ti) surfaces by electrochemical anodization at 10, 30, and 60 V, and the products were denoted as NT10, NT30, and NT60, respectively. NT10 (diameter: 30 nm) and NT30 (diameter: 100 nm) could enhance the HGF functions, such as cell attachment and proliferation and extracellular matrix- (ECM-) related gene expressions, with the latter showing higher enhancement. NT60 (diameter: 200 nm) clearly impaired cell adhesion and proliferation and ECM-related gene expressions. Bacterial adhesion on the TNTs decreased and reached the lowest value on NT30. Therefore, NT30 without pharmaceuticals can be used to substantially enhance the HGF response and reduce P. gingivalis adhesion to the utmost, thus demonstrating significant potential in the transgingival part of dental implants.

Dental implants have become a widely used dental treatment approach. It is important to identify factors that can be detrimental to dental implants and the peri-implant complex. There is controversy regarding whether occlusion plays a role in the implant and peri-implant condition. The present study aims to review the scientific literature regarding this topic. Animal and human studies, and previous reviews on the topic are included and presented. There is a wide heterogeneity among study designs. Several articles demonstrated that occlusion and occlusion overload could detrimentally affect the peri-implant condition, while other articles did not support these results. More studies are needed to help understand the mechanisms by which occlusion might play a role in the peri-implant condition.

Disease of, or trauma to, the human jaw account for thousands of reconstructive surgeries performed every year. One of the most popular and successful treatment options in this context involves the transplantation of bone tissue from a different anatomical region into the affected jaw. Although, this method has been largely successful, the integration of the new bone into the existing bone is often imperfect, and the integration of the host soft tissues with the transplanted bone can be inconsistent, resulting in impaired function. Unlike humans, several vertebrate species, including fish and amphibians, demonstrate remarkable regenerative capabilities in response to jaw injury. Therefore, with the objective of identifying biological targets to promote and engineer improved outcomes in the context of jaw reconstructive surgery, we explore, compare and contrast the natural mechanisms of endogenous jaw and limb repair and regeneration in regenerative model organisms. We focus on the role of different cell types as they contribute to the regenerating structure; how mature cells acquire plasticity in vivo; the role of positional information in pattern formation and tissue integration, and limitations to endogenous regenerative and repair mechanisms.

Introduction. The role of the total lower denture is not only to replace the missing teeth but also to provide the substitute for a range of supporting tissues which have diminished due to the process of resorption, to re-establish the original relations in the region of jaw complex, to support the surrounding soft tissues which have lost their natural support, and, moreover, to be unobtrusive and discrete substitution of lost functions. Application of Mini-dental Implants. If anatomical conditions are unfavorable, there is a wide range of oral-surgical pre-prosthetic procedures which can be performed on both soft tissues and bone structures (vestibuloplasty, alveolar ridge augmentation...) in order to enable proper fabrication of the total lower denture to some extent. Having in mind the old age of the patients, the majority of who suffer from chronic diseases such as diabetes mellitus, cardiovascular problems, systemic diseases etc., these procedures should be avoided because of the extent of the procedure, possible systemic complications and prolonged therapy period. Conclusion. Most recently, the application of titanium endosteal mini implants have proved to be one of good solutions in overcoming unfavorable anatomical conditions resulting in stability and retention of total lower dentures.

The Impact

Objective: To evaluate the impact of soft tissue factors in dental implants. Data: Studies evaluating the role of soft tissues in dental implants were included in this review. Sources: A comprehensive literature search of English and Chinese language articles was performed via electronic databases (PubMed, Cochrane Library, Web of Science, CNKI and VIP) using the appropriate key words(esthetic; evaluation; impact factor; soft tissue). The most recent search took place in January 2016. Study selection: Potentially appropriate articles were identified and evaluated for eligibility through a predefined review process conducted by two examiners. Only 16 out of the 346 identified records met criteria and were included in the final analysis. Conclusion: The success of dental implants depends on two outcomes, the functional utility of the implant and its beauty. During the early phase of treatment, the main objective of a dental implant is to achieve adequate function. In clinical practice, however, subsequent soft tissue retraction and implant exposure have a significantly negative impact on implant esthetics, especially in young women’s teeth, which can also be considered as implant failure. It is particularly important to understand how to support the surrounding soft tissue so that it is esthetically pleasing.

Several factors affect dental implant osseointegration, including surgical issues, bone quality and quantity, and host-related factors, such as patients’ nutritional status. Many micronutrients might play a key role in dental implant osseointegration by influencing some alveolar bone parameters, such as healing of the alveolus after tooth extraction. This scoping review aims to summarize the role of dietary supplements in optimizing osseointegration after implant insertion surgery. A technical expert panel (TEP) of 11 medical specialists with expertise in oral surgery, bone metabolism, nutrition, and orthopedic surgery performed the review following the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews) model. The TEP identified micronutrients from the “European Union (EU) Register of nutrition and health claims made on foods” that have a relationship with bone and tooth health, and planned a PubMed search, selecting micronutrients previously identified as MeSH (Medical Subject Headings) terms and adding to each of them the words “dental implants” and “osseointegration”. The TEP identified 19 studies concerning vitamin D, magnesium, resveratrol, vitamin C, a mixture of calcium, magnesium, zinc, and vitamin D, and synthetic bone mineral. However, several micronutrients are non-authorized by the “EU Register on nutrition and health claims” for improving bone and/or tooth health. Our scoping review suggests a limited role of nutraceuticals in promoting osseointegration of dental implants, although, in some cases, such as for vitamin D deficiency, there is a clear link among their deficit, reduced osseointegration, and early implant failure, thus requiring an adequate supplementation.

The widespread introduction of dental implant in the dental practice will determine progress and the future of prosthetic dentistry. At the same time, like any new direction dental implantation has generated a lot of questions and unsolved problems. On many of these issues and problems can be answered only by using morphological methods. Therefore, after the development of a new construction of the dental implant one of the main issues was the question of its interaction with the jawbone and soft tissues of the oral cavity.We performed the experiment on 24 long snout dogs of both sexes, weighing 30-35 kg, with normal bite, at the age of 20-24 months. Animals were divided into 2 groups, according to samples of screw dental implants used in the experiment: basic group - 12 dogs in which were used samples of the new construction of dental implant “Implant.uz” (Uzbekistan); control group – 12 dogs in which were applied screw dental implant system “Dentium” (South Korea). Terms of derivation of animals from experiments were 1, 3, and 6 months.By using morphological techniques were studied implants “Implant.uz” from medical titanium BT-1.00 brand, their interaction with bone of alveolar ridge. “Implant.uz” did not cause pathological changes in the bone tissue of alveolar ridges of jaws and could be an alternative to known dental implants.
