“…This phenomenon may due to destruction of the blood supply by the creation of a mucoperiosteal flap. Flap elevations may cause a greater number of inflammatory cells, a higher probability of infection, and a longer healing time 49 . Conversely, the meta‐regression analysis in the present review did not establish a significant difference between the flap elevation group and the flapless group regarding their correlation with CHBD or CVBD.…”

Objective: To evaluate the changes in buccal bone dimensions (CBD) following immediate implant placement in the maxillary esthetic zone and to identify the factors influencing the degree of buccal bone resorption for different placement and restoration protocols.Material and methods: An electronic search was conducted using the EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), and MEDLINE (PubMed) databases, combined with a manual and gray literature search, up to January 2021.Selected clinical studies had to report the changes in horizontal buccal bone dimension in maxillary immediate implantation sites (premolar to premolar) at baseline and at follow-up visits within a year of implantation. A meta-analysis was conducted to calculate the mean value of the changes in horizontal and vertical buccal bone dimensions (CHBD and CVBD) around implants. To further investigate the heterogeneity and identify factors associated with buccal bone loss after immediate implant placement, subgroup analysis and univariate meta-regression were performed.Results: From a total of 3498 articles, 4 randomized controlled trials and 12 nonrandomized controlled trials were included for analysis. The mean survival rate of 568 implants was 99.6%. The mean CHBD and CVBD values were 0.71 mm (95% confidence interval: [0.56, 0.86]) and 0.58 mm (95% confidence interval: [0.43, 0.72]), respectively. For possible factors that related to bone resorption, including buccal bone thickness, flap design, bone grafting, horizontal defect dimension, and restoration protocol, bone grafting was the only variable that significantly influenced CHBD.Conclusions: This study demonstrated that immediate implant placement in the esthetic zone does not prevent buccal bone from resorption. Due to data heterogeneity and the small sample size of the studies included in the analysis, further wellconducted, randomized controlled trials with homogeneous samples are required to investigate the correlation of CBD with different variables.

“…It was found that cell inflammatory factors played an important role in ischemia-reperfusion injury, which can lead to tissue morphological damage and dysfunction (10,11). Therefore, anti-inflammatory response is a major research focus aiming to alleviate ischemia-reperfusion injury and improve flap survival rate (12).…”

The aim of the current study was to investigate the effect of SB202190, a specific inhibitor of p38 MAPK signaling pathway, on the expression levels of IL-6 and NF-κB in flap ischemia-reperfusion injury. Healthy Sprague-Dawley rats were randomly divided into four groups of 12 each. For the ischemia-reperfusion group, the flap was constructed and then sutured after 8 h of ischemia. For the saline group, rats were intraperitoneally infused with saline at regular intervals after flap ischemia-reperfusion. For the inhibitor group, rats were intraperitoneally infused with SB202190 at regular intervals after flap ischemia-reperfusion. For the control group, the flap was constructed and then sutured immediately. The flap survival rate of each group was measured after 7 days. The concentration of IL-6 in serum was measured by ELISA kit. The mRNA and protein expression levels of IL-6 and NF-κB in the flap were measured using RT-PCR and western blot analysis, respectively. In the ischemia-reperfusion group and the saline group, the flap survival rates were much lower than that in the control group (P<0.05). By contrast, the mRNA and protein expression levels of IL-6 and NF-κB in the flap and the concentration of IL-6 in serum were much higher (P<0.05). In the inhibitor group, the flap survival rate was significantly higher than those in the ischemia-reperfusion and saline groups (P<0.05). By contrast, the concentration of IL-6 in serum and the mRNA and protein expression levels of NF-κB and IL-6 in the flap were significantly decreased (P<0.05). The results show that, SB202190 played a role in the protection of the flap by reducing the inflammatory response in flap ischemia-reperfusion injury.

“…Although some details can be modified during the performance of the procedure, detailed planning allows for a better clinical outcome. (Al-Juboori, 2016) The main aim of this research was to describe all aspects of surgical manipulation of the soft and hard tissues during the dental implantology procedures. We have made adequate literature research on Pub Med, as most commonly used internet database, for articles relevant to our topic-surgical manipulation of the soft and hard tissues during the dental implantology procedures published in the last two decades , and the type of articles were Clinical Trial, Journal Article, Randomized Controlled Trial, Review, Comparative study and English was chosen as the language and humans as the species.…”

Adequate and correct manipulation of soft and bone tissues during implant therapy is extremelyimportant. Knowledge of the biological, histological and of course the surgical characteristics of the tissues canlargely be a predictor of the correct implant prosthetic rehabilitation. The main aim of this research was to describeall aspects of surgical manipulation of the soft and bone tissues during the dental implantology procedures. We havemade adequate literature research for articles relevant to our topic-surgical manipulation of the soft and hard tissuesduring the dental implantology procedures published in the last two decades (2001-2021). Kew words used for theresearch were: “surgical manipulation”, “dental implantology”, “soft tissues”, “bone tissues” and their combination.Each implantologist should take into account the biological limitations of each patient, as well as the technicallimitations that may occur during the treatment. Oral soft tissues can be affected during the various stages of theimplant treatment. During the planning of a surgical intervention such as the placement of an implant, regardless ofwhether it is an immediate or a delayed loading implant, it is necessary to have an adequate manipulation of thesurrounding soft tissue and bone structures. When designing the flap should be taken into account the degree ofaccessibility required to access the bone, as well as the final position of the flap. It is also of great importance to takeinto account the preservation of good blood supply to the flap. Based on the exposure of bone after elevation, flapscan be classified as either full-thickness or mucoperiosteal flaps and partial-thickness or mucosal flaps. Dependingon how the interdental papilla will be treated, the incisions can either divide the papilla (conventional incision) orpreserve it (papilla-preserving incision). Based on the placement of flaps after surgery, they can be classified as: 1)nondisplaced flaps, where the flap is returned and sutured to its original position, or 2) displaced flaps, which areplaced apically, coronally, or laterally from their original position. The work in bone is quite complex and requiresknowledge of its morphological and histological characteristics. When working on bone, and especially whenplacing dental implants, it is necessary to note that it is necessary to enable constant cooling. The improvement ofold techniques and the development of new technologies have created a revolution in oral implantology, and now atherapist has numerous therapeutic options that can be incorporated into daily practice to facilitate the surgicalapproach itself. Hard-tissue and soft-tissue dental lasers, which are constantly improving and have a wide range ofindications, are becoming a part of everyday dental practice and also show significant advantages compared toconventional instruments and techniques when placing dental implants. Therefore, over time they will become aninvaluable and irreplaceable tool in modern dental implantology. After the performed extensive and deductiveliterature review, it can be concluded that from particular importance is the correct manipulation of soft and bonetissues during dental implantation. After tooth extraction, the placement of dental implants is largely determined bythe integrity of existing hard and soft tissues, such as the aesthetic outcome from the prosthodontic suprastructureover dental implants. Careful assessment of soft and bone tissue loss during implantation is paramount to the successof aesthetic implant procedures
