SMILE REHABILITATION IN ANTERIOR AESTHETIC ZONE USING BASAL IMPLANT

Aesthetics are one of the primary goals of restorative care. Teeth that are traumatized in the anterior maxilla usually avulse or require extraction due to fractures. Rehabilitation is challenging in such a therapeutic state since it presents several anatomical and aesthetic issues. There are circumstances in which traditional implant placement is problematic. There must be enough bone for implant placement to be uneventful and successful. Other surgical therapies may be necessary in addition to implant placement for certain operations, such as extensive grafting, direct or indirect sinus lifts, and nerve lateralization. Certain procedures are required for these operations but are not always achievable. Because single-piece basal implants provide immediate temporization and loading while receiving adequate anchoring from the basal cortical bone, they have been extensively used to rehabilitate resorbed ridges. This case report demonstrates the placement of the basal implant in the anterior zone.

Direct Sinus Lift with Immediate Implant Placement- A Modality in Atrophied Maxilla: A Case Report

The pneumatization of the maxillary sinus poses challenges for oral implantologists due to its natural expansion into the maxillary bone, often exacerbated by tooth loss. This reduces available bone for implant placement in the posterior maxilla, necessitating augmentation techniques to facilitate successful implantation. This article presents the case of a 23-year-old female with severe tooth decay in the left maxilla, desiring implant replacement. Cone-beam computed tomography (CBCT) revealed inadequate bone height (3.3 mm) complicated by sinus pneumatization. Surgical intervention involved tooth extraction followed by direct sinus augmentation with a bone graft to stimulate osteogenesis. Simultaneously, an implant was placed. Follow-up CBCT examination occurred at the 4-month interval. At the 4-month follow-up, CBCT examination demonstrated a significant increase in vertical bone height to 12.4 mm, indicating successful bone regeneration and implant stability. The case highlights the importance of a comprehensive diagnostic approach and strategic surgical planning in managing sinus pneumatization-related challenges for implant placement. Direct sinus augmentation combined with bone grafting proved effective in achieving sufficient bone height for implantation. This underscores the significance of appropriate therapeutic interventions and postoperative monitoring for favorable outcomes in such cases.

Fruit fly optimization algorithm with escape predation mechanism based direct lift control for automatic carrier landing

This paper designs a practical automatic carrier landing system (ACLS) that utilizes direct lift control (DLC) technology, and the controller parameters are optimized by using the enhanced fruit fly optimization algorithm with escape predation mechanism (EPFOA). The designed ACLS comprises the control channels of elevator, flap and throttle. The coordinated action of the elevator and flap can generate direct lift, enabling the aircraft to approach the desired glide path quickly and accurately. A decoupling module is designed to enhance the attitude stability of the aircraft during landing, thereby increase the success rate of landing. In order to achieve the better control effectiveness, the EPFOA is proposed to optimize the controller parameters of the DLC-based ACLS. Inspired by the predator-escape behavior between dingoes and sheep, EPFOA divides the whole fruit fly swarm into three categories: discovered escaping fruit fly (DEF), escaping fruit fly (EF) and predator fruit fly (PF). The PFs can ensure the population of convergence, while the DEFs and EFs can preserve the diversity of the population and avoid falling into local optima. Experiments are conducted in various cases, and the designed DLC-ACLS demonstrates superior ability in flight path adjustment and attitude control compared to the traditional F/A-18 ACLS in landing control. Additionally, the proposed EPFOA shows superior performance compared to other optimization algorithms.

Fault-tolerant control of automatic carrier landing using direct lift control based on nonsingular terminal sliding mode and active disturbance rejection control

This paper presents a fault-tolerant control scheme, combining nonsingular terminal sliding mode and active disturbance rejection control (NTSM-ADRC) to address actuator failure and external disturbances during the automatic carrier landing process of a carrier-based aircraft using direct lift control (DLC). First, the carrier-based aircraft model, the carrier air-wake model, and the actuator fault model were established. Second, the NTSM-ADRC controller is designed, The unmodeled dynamics of the system, the air-wake disturbance, and the fault term are treated as total disturbances and estimated accurately by extended state observer (ESO). To improve the response characteristics of the controller, the nonlinear error feedback control law is designed by combining the NTSMC. The Lyapunov function is constructed to prove the stability of the closed-loop system. The controller is applied to the aircraft DLC channel, attitude auxiliary channel, and approach power compensation system. The DLC improves the performance of fixed-wing aircraft by directly generating high lift through the flaps to change the aircraft trajectory. Finally, the method is tested by introducing various types of actuator failures. Simulation results demonstrate that the designed longitudinal fault-tolerant carrier landing system exhibits strong robustness and fault tolerance, thereby improving the accuracy of aircraft landing trajectory tracking.

Forehead flap perfusion monitored by laser speckle contrast imaging: Importance of flap length and thickness

PurposeForehead flaps are commonly used in oculoplastic surgery to cover defects after tumor excision. Blood perfusion is vital for flap survival. The aim of this study was to monitor the perfusion in forehead flaps and investigate the impact of flap length and thickness. MethodsNineteen forehead flaps in patients undergoing direct brow lift were studied. Perfusion was monitored using laser speckle contrast imaging, immediately after raising flaps consisting of epidermis, dermis, and subcutaneous tissue, and after removing the subcutaneous tissue resulting in a thin flap. ResultsPerfusion decreased gradually along the length, the mean value being 44% at 5 mm and 26% at 15 mm from the base, in thick flaps. Perfusion was significantly lower in thin flaps, being 13% when measured 15 mm from the flap base (p < 0.0024). Perfusion was better preserved in thick than in thin flaps. Very low perfusion was observed 16.7 mm (16.0–17.3 mm) from the base in thick flaps, and from 10.2 mm (9.8–10.6 mm) from the base in thin flaps (p < 0.0001). ConclusionsFlap thickness is important in maintaining adequate blood perfusion and thus increasing the probability of flap survival. This may be particularly important in long flaps and in patients with impaired microcirculation.

Fault-Tolerant Control for Carrier-Based Aircraft Automatic Landing Subject to Multiple Disturbances and Actuator Faults

This paper introduces a fault-tolerant control scheme for the automatic carrier landing of carrier-based aircraft using direct lift control. The scheme combines radial basis function neural network and active disturbance rejection control (RBF-ADRC) to overcome the impact of actuator failures and external disturbances. First, the carrier-based aircraft model, the carrier air-wake model, and the actuator fault model were established. Secondly, ADRC is designed to estimate and compensate for actuator faults and disturbances in real time. RBFNN adjusts the ADRC controller parameters based on the system state. Then, the Lyapunov function is constructed to prove the stability of the closed-loop system. The controller is applied to the direct lift control channel, auxiliary attitude channel, and approach power compensation system. The direct lift control improves the performance of fixed-wing aircraft. Finally, comparative simulations were conducted under various actuator failures. The results demonstrate the remarkable fault tolerance of the RBF-ADRC scheme, enabling precise tracking of the desired glide path by the shipboard aircraft even in the presence of actuator failures.

The Seven Step Neck Lift Z-Plasty.

Patients with large amounts of neck skin redundancy who do not desire or are not candidates for traditional face and neck lifts can be managed with direct neck lifts. There are many existing surgical techniques to address central neck laxity. In this article, we aim to clarify our surgical technique in a clear video format to showcase how to address central neck laxity in seven steps with neck lift Z-plasty.

Rejuvenation in Men Facial Aging: A Combined Approach.

Facelift surgery, also known as rhytidectomy, is a popular cosmetic procedure aimed at reversing the signs of facial aging. While facelift surgery is more commonly performed in women, an increasing number of men are seeking this procedure to maintain a youthful appearance. The long recovery period conflicts the overall primary outcome anticipated by men undergoing rhytidectomy, i.e., appear younger, youthful, and ready to reaffirm their value in the working environment. Anterior direct neck lift, blepharoplasty (upper and lower eyelid blepharoplasty), and lipofilling are three techniques that have been shown to be effective in improving facial rejuvenation outcomes in elderly male patients. However, there is little to no evidence of the safety and efficacy of these techniques when used in combination. By combining these techniques, we hypothesized that we could achieve outcomes comparable to traditional facelift surgery, but with a lower risk of complications and a shorter recovery time. We conducted a retrospective case series study of 18 male patients who underwent facial rejuvenation surgery using the combination of anterior direct neck lift, blepharoplasty (upper and lower eyelid blepharoplasty), and lipofilling at our institution between 2018 and 2021. All 18 patients completed the study, with an average follow-up of 12months. No major complications were observed, and all patients reported a high level of satisfaction with their outcomes.Level of Evidence IV This journal requires that authors assign a level of evidence to each article.

Direct brow lift – indications, diagnostics, operating techniques

Eyebrow lift is one of the most effective rejuvenating procedures in facial plastic surgery. Lifting the aging soft structures around the eye socket yields both cosmetic and, in some cases, therapeutic effects. Regardless of the indications, preoperative assessment of the patient should be based on a thorough interview, establishing the patient’s expectations, determining the achievable outcome of the procedure, and anticipating potential complications. During the physical examination, it is crucial to identify relevant anatomical structures, assess facial symmetry, scope, and the technique of the procedure. Often, patients opt for combining direct eyebrow lift with eyelid surgery, significantly enhancing the overall result. The primary complication of direct eyebrow lifting is a visible scar, which may be a contraindication for individuals prone to keloid formation and those with a brow deficit. The aim of this study is to define the indications, diagnostics, and describe the surgical techniques used in eyebrow lift procedures.

Comparison of the Effectiveness of the Miller Laryngoscope and the McGrath-MAC Video Laryngoscope in Direct Visualization of the Glottic Opening.

Background and Objective: Placing the laryngoscope blade directly under the epiglottis (known as the direct view (DV) method) during videolaryngoscopy offers a superior view of the glottis when compared to the indirect method of lifting the epiglottis by positioning the Macintosh blade tip over the vallecula. While there are few studies comparing glottic views using Miller and Macintosh blades in pediatric patients, we have not come across such a study in adults. In this study, we aimed to compare the effectiveness and hemodynamic responses of the Miller laryngoscope and the McGrath-MAC videolaryngoscope (VL) in visualizing the glottic opening using the DV method. Material and Methods: A prospective study was conducted between August and December 2022 at XXX Hospital on 85 patients scheduled for surgical procedures involving endotracheal intubation. Patients were divided into two groups: Miller laryngoscope (Group M) and McGrath-MAC videolaryngoscope (Group VL) and intubated using the direct lifting method of the epiglottis. Hemodynamic responses before and after induction, as well as during laryngoscopy, intubation time, number of attempts, Cormack and Lehane (C&L) score, percentage of glottic opening (POGO), duration of the view of the opening, and need for external laryngeal pressure during intubation were recorded. Results: Both laryngoscopes showed similar effectiveness in terms of POGO and C&L score when used with the direct lifting method of the epiglottis. The median POGO values according to the DV method were 80% in Group M and 70% in Group VL (p = 0.099). Hemodynamic responses, intubation time, number of attempts, duration of view of the glottis opening, and the need for external laryngeal pressure were similar between the groups. Conclusions: Due to its ability to provide effective intubation conditions, we believe that the McGrath-MAC VL, when used with the indirect view method, can also be utilized in anesthesia practices alongside the DV method.

Blepharospasm Secondary to Deep Brain Stimulation of the Subthalamic Nucleus in Parkinson Disease: Clinical Characteristics and Management Outcomes.

Deep brain stimulation of the subthalamic nucleus (STN-DBS) is an effective treatment for patients with motor symptoms of Parkinson disease but can be complicated by disabling blepharospasm and apraxia of eyelid opening (ALO). Currently, there is no clear consensus on optimal management, and addressing these issues is further hindered by systemic morbidity and resistance to treatments. We aim to describe the different phenotypes of these eyelid movement disorders, to report our management approach and patient responses to treatment. A retrospective case series of all patients with blepharospasm/ALO secondary to STN-DBS that were treated at a tertiary center between 2011 and 2020. Data collected included date of Parkinson diagnosis, date of DBS surgery, date of development of blepharospasm/ALO symptoms, STN-DBS stimulation settings, and treatment given. Patients' symptoms before and after treatment were measured using the blepharospasm disability index and Jankovic Rating Scale. Five patients were identified with eyelid movement disorders secondary to STN-DBS. All patients had moderate-to-severe symptoms at presentation. Four patients received periocular botulinum toxin injections. Three patients underwent surgery in the form of frontalis suspension or direct brow lift with or without upper lid blepharoplasty. All reported an improvement in symptoms following treatment. A multimodality, patient-specific approach is required in the treatment of blepharospasm/ALO secondary to STN-DBS. Botulinum toxin injections can be effective, but patients may require surgery if toxin treatment alone becomes ineffective. Tailoring treatment to individual needs can result in a measurable improvement in symptoms.

Comparison of Pathologic Changes in the Maxillary Sinus Before and After Dental Implant Surgery Using Cone Beam Computed Tomography.

To examine the changes of dentoalveolar structures and pathologies in the maxillary sinus before and after dental implant surgery alone or with direct vs indirect sinus lifting using CBCT images of the maxillary posterior region. Preoperative and postoperative CBCT images of 50 sinus sites and the alveolar bone around 83 implants in 28 patients were evaluated. Maxillary sinus pathologies were classified as mucosal thickening (MT), mucus retention cyst (MRC), polyp, and sinusitis before and after surgery. The changes after surgery were determined to be no change, reduction in pathology, or increase in pathology. Comparisons of pathology changes among the treatment groups were evaluated statistically with chi-square test, McNemar test, and Mann-Whitney U test. Of the 50 sinuses evaluated for the presence of sinus pathology, 24 of 50 did not change postoperatively, the pathology increased in 10 sinuses, and the pathology decreased in 16. When the maxillary sinus regions were evaluated after indirect sinus lifting, direct sinus lifting, and in patients who had only implant surgery, there was no statistically significant difference between pathology distribution in terms of the procedure applied to the sinus (P > .05). However, in the maxillary sinuses with a pathology before implant placement were evaluated postoperatively, a statistically significant difference was found in favor of the presence of a change in pathology (ie, improvement or a decrease; P < .05). The maxillary sinuses without pathology before implant placement showed a statistically significant difference for no change; ie, continuation of the healthy state (P < .05). This study showed that surgical procedures could have a direct effect on the sinus membrane and maxillary sinus. Both the implant procedure and surgical approach may have an effect on maxillary sinus pathology, as well as an increase or decrease of the pathology. Hence, further studies with a longer-term follow-up should be performed to better understand the correlation between implant surgery and pathology.

Direct brow lift surgical technique and new eyebrow aesthetic optimization model

The fascination with beauty attracts optimizations of surgical techniques. The eyelid-eyebrow region forms the emotional and expressive center of the human face. Aging causes a decrease in skin elasticity, allowing soft tissues to sag with gravity [1,2]. In this sense, surgical eyebrow lifts to improve aesthetics of the upper third of the aging face have been performed for several years. Current brow lift methods include direct brow lift, mid-forehead lift, coronal brow lift, and endoscopic brow lift [3-5]. Therefore, this technical article presents an optimization of the treatment of eyebrow tail ptosis using the modified direct brow lift technique by direct eyebrow elevation.

Hyperangulated blades or direct epiglottis lifting to optimize glottis visualization in difficult Macintosh videolaryngoscopy: a non-inferiority analysis of a prospective observational study

PurposeIt is unknown if direct epiglottis lifting or conversion to hyperangulated videolaryngoscopes, or even direct epiglottis lifting with hyperangulated videolaryngoscopes, may optimize glottis visualization in situations where Macintosh videolaryngoscopy turns out to be more difficult than expected. This study aims to determine if the percentage of glottic opening (POGO) improvement achieved by direct epiglottis lifting is non-inferior to the one accomplished by a conversion to hyperangulated videolaryngoscopy in these situations.MethodsOne or more optimization techniques were applied in 129 difficult Macintosh videolaryngoscopy cases in this secondary analysis of a prospective observational study. Stored videos were reviewed by at least three independent observers who assessed the POGO and six glottis view grades. A linear mixed regression and a linear regression model were fitted. Estimated marginal means were used to analyze differences between optimization maneuvers.ResultsIn this study, 163 optimization maneuvers (77 direct epiglottis lifting, 57 hyperangulated videolaryngoscopy and 29 direct epiglottis lifting with a hyperangulated videolaryngoscope) were applied exclusively or sequentially. Vocal cords were not visible in 91.5% of the cases with Macintosh videolaryngoscopy, 24.7% with direct epiglottis lifting, 36.8% with hyperangulated videolaryngoscopy and 0% with direct lifting with a hyperangulated videolaryngoscope. Conversion to direct epiglottis lifting improved POGO (mean + 49.7%; 95% confidence interval [CI] 41.4 to 58.0; p &amp;lt; 0.001) and glottis view (mean + 2.2 grades; 95% CI 1.9 to 2.5; p &amp;lt; 0.001). Conversion to hyperangulated videolaryngoscopy improved POGO (mean + 43.7%; 95% CI 34.1 to 53.3; p &amp;lt; 0.001) and glottis view (mean + 1.9 grades; 95% CI 1.6 to 2.2; p &amp;lt; 0.001). The difference in POGO improvement between conversion to direct epiglottis lifting and conversion to hyperangulated videolaryngoscopy is: mean 6.0%; 95% CI −6.5–18.5%; hence non-inferiority was confirmed.ConclusionWhen Macintosh videolaryngoscopy turned out to be difficult, glottis exposure with direct epiglottis lifting was non-inferior to the one gathered by conversion to hyperangulated videolaryngoscopy. A combination of both maneuvers yields the best result.Clinical trial registrationClinicalTrials.gov, NCT03950934.

Directional lifting wavelet transform for image edge analysis

In this paper, we propose a new two-dimensional directional discrete wavelet transform that can decompose an image into 12 multiscale directional edge components. The proposed transform is designed in a fully discrete setting and thus is easy to implement in actual computations. The proposed transform is viewed as a category of redundant discrete wavelet transforms implemented by fast in-place computational algorithms by a lifting scheme that has been modified to incorporate redundancy. The redundancy is limited to (N×J+1)/4, where N=12 is the directional selectivity and J is a decomposition level of the multiscale transform. Numerical experiments in edge analysis using various images demonstrate the advantages of the proposed method over some conventional standard methods. The proposed method outperforms several conventional edge detection methods in identifying both the location and orientation of edges, and well captures the directional and geometrical features of images.

Research on Direct Lift Carrier-Based Unmanned Aerial Vehicle Landing Control Based on Performance Index Intelligent Optimization/Dynamic Optimal Allocation

High-precision control problems for carrier-based UAVs are challenging due to the requirements for safety, high-performance operation and uncertain ocean environments. To address such problems, this paper proposes a direct lift landing control method that can ensure the safe operation of UAVs using intelligent optimization of control performance indicators and dynamic optimal allocation methods. The direct lift control (DLC) scheme is adopted to improve the operability of the control by introducing flap channels to achieve the fast correction of vertical disturbances. To improve the landing control performance, an intelligent optimization method for DLC gain is proposed, and a neural network relationship between parameter uncertainty and optimal DLC gain is established. In addition, a recursive least-squares identification method is used to estimate the uncertain parameters in real time, so that the established neural network can be used to generate the optimal DLC commands online, and the generated control commands can be assigned to multiple actuators of the carrier-based UAV through a dynamic optimal assignment algorithm. Finally, the superiority of the method is verified using simulation comparison.

Oxygen saturation mapping during reconstructive surgery of human forehead flaps with hyperspectral imaging and spectral unmixing

BackgroundOptical spectroscopy is commonly used clinically to monitor oxygen saturation in tissue. The most commonly employed technique is pulse oximetry, which provides a point measurement of the arterial oxygen saturation and is commonly used for monitoring systemic hemodynamics, e.g. during anesthesia. Hyperspectral imaging (HSI) is an emerging technology that enables spatially resolved mapping of oxygen saturation in tissue (sO2), but needs to be further developed before implemented in clinical practice. The aim of this study is to demonstrate the applicability of HSI for mapping the sO2 in reconstructive surgery and demonstrate how spectral analysis can be used to obtain clinically relevant sO2 values. MethodsSpatial scanning HSI was performed on cutaneous forehead flaps, raised as part of a direct brow lift, in eight patients. Pixel-by-pixel spectral analysis, accounting for the absorption from multiple chromophores, was performed and compared to previous analysis techniques to assess sO2. ResultsSpectral unmixing using a broad spectral range, and accounting for the absorption of melanin, fat, collagen, and water, provided a more clinically relevant estimate of sO2 than conventional techniques, where typically only spectral features associated with absorption of oxygenated (HbO2) and deoxygenated (HbR) hemoglobin are considered. We demonstrate its clinical applicability by generating sO2 maps of partially excised forehead flaps showed a gradual decrease in sO2 along the length of the flap from 95 % at the flap base to 85 % at the flap tip. After being fully excised, sO2 in the entire flap decreased to 50 % within a few minutes. ConclusionsThe results demonstrate the capability of sO2 mapping in reconstructive surgery in patients using HSI. Spectral unmixing, accounting for multiple chromophores, provides sO2 values that are in accordance with physiological expectations in patients with normal functioning microvascularization. Our results suggest that HSI methods that yield reliable spectra are to be preferred, so that the analysis can produce results that are of clinical relevance.

The Importance of Median Glossoepiglottic Fold Engagement on Laryngeal View and Tracheal Intubation Success in Children.

Our study objective was to determine if the location of laryngoscope blade tip placement is associated with clinically important tracheal intubation outcomes in a pediatric emergency department. We conducted a video-based observational study of pediatric emergency department patients undergoing tracheal intubation with standard geometry Macintosh and Miller video laryngoscope blades (Storz C-MAC, Karl Storz). Our main exposures were direct lifting of the epiglottis versus blade tip placement within the vallecula and median glossoepiglottic fold engagement versus not when the blade tip was placed in the vallecula. Our main outcomes were glottic visualization and procedural success. We compared measures of glottic visualization between successful and unsuccessful attempts using generalized linear mixed models. Proceduralists placed the blade tip in the vallecula (indirectly lifting the epiglottis) during 123 (71.9%) of 171 attempts. When compared with indirectly lifting the epiglottis, directly lifting the epiglottis was associated with improved visualization-by percentage of glottic opening (POGO) (adjusted odds ratio [AOR], 11.0; 95% confidence interval [CI], 5.1 to 23.6) and modified Cormack-Lehane (AOR, 21.5; 95% CI, 6.6 to 69.9). When in the vallecula, engagement of the median glossoepiglottic fold was associated with improved POGO (AOR, 3.6; 95% CI, 1.9 to 6.8), modified Cormack-Lehane (AOR, 3.9; 95% CI, 1.1 to 14.1), and success (AOR, 9.9; 95% CI, 2.3 to 43.7). Emergency tracheal intubation can be performed in children at a high level by directly or indirectly lifting the epiglottis. If indirectly lifting the epiglottis, median glossoepiglottic fold engagement is helpful in maximizing glottic visualization and procedural success.

Comparison of pre and post-operative stresses among Indian patients undergoing intra-oral grafting procedures.

With the advent of implantology as an important means to rehabilitate the edentulous patients, the neglect over the years post extraction leads to severe bone loss. This can be corrected by grafting procedures. Grafting procedures are complex as it takes into account various factors such as the type of graft material, surgical site, surgeon's skill and the patient's compliance. Totally 20 patients ( male n=10 ; female n=10) were included in the study, 14 patients underwent GBR, 4 patients underwent direct sinus lifts and 2 underwent block grafts. The stress levels of the patient also is an important factor to consider as varying cortisol levels will be detrimental to the healing of the surgical site. Premedication with painkillers and corticosteroids can help patients comply with the treatment and feel less anxious. The stress levels of the patient were assessed using State trait anxiety index, 50.6± 6.9 was the pre-operative stress and 36.95± 9.3 was the post-operative stress. Stress levels were significantly greater before the procedure than after it, according to statistical analysis. The females were significantly having increased stress both pre and post-operatively. Also, the patients in the age group of 41-50 years showed increased amounts of stress.

Clinical, Radiographic, and Histological Evaluation of the Mineralized Plasmatic Matrix/Xenograft Mixture in Maxillary Sinus Floor Augmentation (A Randomized Controlled Clinical Trial)

Introduction: Maxillary sinus pneumatization and alveolar ridge resorption following the extraction of posterior teeth make the installation of dental implants in the maxillary posterior region challenging. The direct sinus lift procedure proved to be a viable treatment option for such conditions. Aim of the study: to evaluate the mineralized plasmatic matrix/xenograft mixture in sinus elevation surgery. Materials and Methods: Eighteen patients were selected and randomly allocated into two groups; study group received a mineralized plasmatic matrix/xenograft mixture, while the control group received xenograft alone following sinus lifting. Results: The early wound healing index score showed a non-significant difference between both groups. Also, bone height was evaluated at the 6-month follow-up period, and there was a non-statistically significant difference. Core biopsies were taken for histological examination by H&amp;E from both groups, revealing the presence of a more mature bone matrix in relation to the test group. Conclusion: The addition of mineralized plasmatic matrix to xenograft can speed up bone formation, thus reducing treatment duration.
