Global prevalence of perinatal depression and anxiety during the COVID-19 pandemic: An umbrella review and meta-analytic synthesis.

INTRODUCTION: The prevalence of depression and anxiety symptoms in pregnant and postpartum women during the COVID-19 pandemic was assessed by several systematic reviews (SRs) and meta-analyses which provided contrasting and different results. We aimed to summarize the evidence relating to the global prevalence of anxiety and depression among pregnant and postpartum women during the COVID-19 pandemic. MATERIAL AND METHODS: An umbrella review of SRs and meta-analyses was performed. Searches were conducted in electronic databases up to April 2023. SRs and meta-analyses reporting the prevalence of perinatal anxiety and depression during the COVID-19 pandemic were selected for eligibility. Primary studies extracted from eligible meta-analyses were included in the quantitative synthesis. The research protocol was registered on PROSPERO (CRD42020173125). RESULTS: A total of 25 SRs (198 primary studies) and 12 meta-analyses (129 primary studies) were included in the qualitative and quantitative synthesis, respectively. Studies involved data from five continents and 45 countries. The pooled prevalence of antenatal and postpartum depression was 29% (n = 55; 95% CI: 25%-33%) and 26% (n = 54; 95% CI: 23%-30%), respectively. In the case of anxiety, the pooled antenatal and postnatal prevalence was 31% (n = 44; 95% CI: 26%-37%; n = 16; 95% CI: 24%-39%). Differences emerged between continents, with Africa having the highest prevalence of perinatal depression and Oceania and Europe having the highest prevalence of antenatal and postnatal anxiety. The prevalence also varied depending on the assessment tools, especially for antenatal anxiety. A medium-high quality of the studies was observed. One SR assessed strength-of-evidence, reporting very low strength. CONCLUSIONS: During the COVID-19 pandemic, depression and anxiety were common, affecting almost one in three perinatal women globally. A high heterogeneity and a risk of publication bias were found, partially due to the variety of assessment tools and cut-offs. The results may not be generalized to minorities. Studies on the prevalence of clinical diagnoses are needed. Based on our results it is not possible to firmly affirm that the COVID-19 pandemic was the main factor that directly increased perinatal depression and anxiety during the past few years. Future studies should study other factors' impact.

COVID-19 Posttraumatic Effects on Perinatal Psychological Distress: A Cross-Sectional Study at the End of the Pandemic Health Emergency.

INTRODUCTION: Psychological distress in pregnant and postpartum women increased during the COVID-19 pandemic. However, the impact of the pandemic in perinatal women at the end of the health emergency has been rarely studied. This study is aimed at investigating the psychological health of pregnant and postpartum women at the end of the COVID-19 public health emergency, hypothesizing that the COVID-19-related fears influence perinatal psychological distress via the mediation of the COVID-19-related posttraumatic impact and loneliness. METHODS: A total of 200 women in the perinatal period, of which 125 were pregnant and 75 were postpartum, participated in an online survey at the end of the COVID-19 public health emergency in Italy. Depression, anxiety, stress, loneliness, posttraumatic impact of COVID-19 pandemic and COVID-19-related fears were assessed. To test the hypotheses, robust serial mediation analyses were performed. RESULTS: Increased levels of COVID-19-related fears were associated with an increase in perinatal depression, anxiety and stress indirectly through the serial mediation of COVID-19 posttraumatic impact and loneliness. Loneliness played a stronger role in mediating the relationship between COVID-19-related fears and depression than anxiety and stress outcomes. CONCLUSIONS: This study should be considered exploratory for its methodological characteristics and nonreplicability of the pandemic condition. However, this study suggests the importance of assessing posttraumatic reactions to 'collective' crises in pregnant and postpartum women for research and clinical practice. In addition, it sustains the role of loneliness as a transversal construct that should be greatly considered in targeting psychological interventions for women in the perinatal period.

Clinical and radiographic evaluation of implant-supported single-unit crowns with cantilever extensions: A systematic review and meta-analysis.

PURPOSE: The purpose of this systematic review and meta-analysis was to analyze the clinical and radiographic outcomes of patients rehabilitated using a single implant supporting a crown with a cantilever extension or two implants supporting two single crowns. METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) 2020 guidelines, a systematic review of relevant literature published from 2000 was conducted in the Cochrane Library, Scopus, and MEDLINE databases. Moreover, a manual search was performed. A meta-analysis of the resulting data was carried out. Peri-implant marginal bone level, probing pocket depth, prevalence of technical and mechanical complications, implant survival rate, and prosthesis survival rate were assessed. RESULTS: The meta-analysis showed a non-statistically significant change in the peri-implant marginal bone level and probing pocket depth in the cantilever group and revealed a non-significant prevalence of technical complications, showing a 27% rate in the cantilever group. The analysis of the prosthesis survival rate in the cantilever group showed a mean survival rate of 99% while the comparison of the implant survival between the two groups revealed an odds ratio of 0.50. CONCLUSIONS: The use of a single implant supporting a crown with a cantilever extension does not result in lower implant survival rate if compared with two implants supporting two single crowns. Moreover, a high prosthesis survival rate was observed in the cantilever group even if the high prevalence of complications should be carefully considered by the clinician.

An observatory on changes in dreaming during a pandemic: a living systematic review (part 1).

A 'new' way of dreaming has emerged during the pandemic, enhancing the interest of psychological literature. Indeed, during the years of the spread of coronavirus disease 2019 (COVID-19), many studies have investigated dream-related phenomena and dreaming functions. Considering the constant and rapid emergence of new results on this topic, the main aim of this study was to create an 'observatory' on the short- and long-term consequences of the COVID-19 pandemic on dreaming, by means of a living systematic review. The baseline results are presented, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement guidelines, to identify and discuss existing studies about dreams and dreaming during the COVID-19 pandemic published until February 2022. Web of Science, Embase, EBSCO, and PubMed were used for the search strategy, yielding 71 eligible papers included in the review. Our results show: (a) a more intense oneiric activity during lockdown; (b) changes in dreaming components (especially dream-recall and nightmare frequency); (c) a particular dreaming scenario ('pandemic dreams'); (d) an alteration of the dreaming-waking-life continuum and a specific function of dreaming as emotional regulator. Findings suggest that monitoring changes in dreaming provides important information about psychological health and could also contribute to the debate on the difficulties of dreaming, as well as sleeping, in particular during and after a period of 'collective trauma'.

The time of motherhood in a time of crisis: a longitudinal qualitative study.

AIMS/BACKGROUND: The impact of the COVID-19 pandemic on the health of women in the perinatal period has been widely shown in literature. Although longitudinal quantitative studies investigated the long-term effects of the COVID-19 pandemic on both women and children's health, no longitudinal qualitative study can be found within literature. The study aimed at an in-depth exploration of the longitudinal trajectories, from pregnancy to postpartum, lived by women through the waves of the COVID-19 pandemic in Italy. DESIGN/METHODS: As a method, the qualitative approach of Longitudinal Interpretative Phenomenological Analysis was used. A total of 14 women were interviewed for the first time during pregnancy (March-May 2021/second wave of the COVID-19 spread). Among the total, 8 completed a second interview, one year later, during postpartum (March-May 2022/end of the COVID-19 public emergency) and were included in the analysis. RESULTS: Three superordinated themes emerged: (1) Maternal functions during the COVID-19 pandemic; (2) 'Care' needs of women in maternal services; (3) Unspeakable: obstetric violence and gender inequality in the working field. Themes were organised considering women's experience, showing continuity and discontinuity paths overtime. CONCLUSION: Women in their perinatal period during the COVID-19 pandemic felt like 'living incubators', both isolated and invested in individual and social responsibilities of 'caring'.The study confirms the need to re-centre maternal care services' praxis on women's needs as an act of collective repair against the consequences of collective trauma of the COVID-19 pandemic.

Female Nigerian asylum seekers in Italy: An exploration of gender identity dimensions through an interpretative phenomenological analysis.

We present a qualitative study exploring the subjective meanings that five female Nigerian asylum seekers hosted in Italy attributed to their pre-migratory, migratory and post-migratory experiences, with an examination in-depth of the gender identity dimensions. We developed and administered semi-structured interviews, analyzed according to the Interpretative Phenomenological Analysis. On the background of the identity breakdown produced by forced migration, we highlight an inadequate integration process of the gender roles of woman and mother, generating a fracture that makes women's experiences particularly fragile. Reflections on the implication of the study and of the development of intervention programs will be outlined.

Self-harming behaviours of asylum seekers and refugees in Europe: A systematic review.

The increasing number of asylum seekers and refugees in Europe calls for even more professionals to take care of refugees' mental health. Although different studies claim that migration could be a potential risk factor for self-harming behaviours, an in-depth exploration of the presence and characteristics of self-harm in the context of asylum is needed. In accordance with PRISMA guidelines, a systematic review was conducted across the databases Scopus, PubMed, Web of Knowledge and PsycArticles, regarding the main features of self-harming behaviour among refugees in Europe. Twelve articles and 3 main trajectories were identified: (1) A context at-risk: self-harm and detention centres; (2) A target at-risk: self-harm and unaccompanied minors; (3) A comparison between the mental health of asylum seekers and natives. Research on this topic in Europe is still underdeveloped and disorganised. Studies have mainly carried out wider quantitative investigations on mental health, usually overlapping self-harm with suicide. Detention centres emerged as the most widely investigated context and the one with the highest risk for self-harming behaviours. Instead, unaccompanied minors emerged as a particularly vulnerable category. Research in this field should be improved, combining quantitative and qualitative methods for a deeper understanding of the meanings of self-harm across cultures.

Hard and Soft Tissue Evaluation of Different Socket Preservation Procedures Using Leukocyte and Platelet-Rich Fibrin: A Retrospective Clinical and Volumetric Analysis.

PURPOSE: The extraction of a tooth is followed by hard and soft tissue changes that can compromise implant placement. The aim of the present retrospective study was to compare the clinical and radiographic outcomes of different ridge preservation procedures based on the use of leukocyte and platelet-rich fibrin (L-PRF). MATERIALS AND METHODS: The study population consisted of all patients who had undergone surgery from January 1, 2017 to January 1, 2018 for alveolar ridge preservation on single posterior teeth using 3 clinical protocols: L-PRF alone, L-PRF mixed with a bone xenograft, and bone xenograft alone. Clinical and radiographic measures were recorded preoperatively and at 6 months postoperatively to determine the horizontal and vertical ridge resorption. RESULTS: A total of 45 patients were included in the present study. All the surgeries were performed successfully, and no intraoperative complications developed. The L-PRF group experienced significantly greater horizontal and vertical bone resorption. The L-PRF plus bone xenograft group had less vertical and horizontal bone resorption than the bone xenograft alone group. Statistically significant differences in postoperative pain and wound healing were observed, with the bone xenograft alone group, in particular, having higher values for pain and experiencing delayed wound healing. CONCLUSIONS: Within the limitations of the present retrospective study, the use of a bone xenograft alone or L-PRF combined with a bone xenograft to perform alveolar ridge preservation procedures significantly limited bone resorption.

A Comparison of Guided Bone Regeneration vs. the Shell Technique Using Xenogeneic Bone Blocks in Horizontal Bone Defects: A Randomized Clinical Trial.

In cases of severe horizontal atrophy, implant placement requires bone reconstruction procedures. The aim of this randomized controlled trial is to compare the outcomes of bone augmentation with simultaneous implant placement using the shell technique to the outcomes of guided bone regeneration (GBR) in cases of severely horizontal bone atrophy. This study was designed as a monocentric, parallel-group, randomized controlled trial with a six-month follow-up. Among the primary outcomes of this study, peri-implant bone regeneration and peri-implant bone defect closure were selected. Forty-four patients were recruited and equally divided between two groups. In the GRB group, a horizontal regeneration of 2.31 ± 0.23 mm was observed opposed to a horizontal regeneration of 2.36 ± 0.17 mm in the shell group (p = 0.87). A volumetric increase was observed in both groups, with an increase of 0.30 ± 0.12 cm3 in the GBR group and an increase of 0.39 ± 0.09 cm3 in the shell group, highlighting a significant difference between the two groups (p = 0.02). In conclusion, bone augmentation with simultaneous implant placement using the shell technique or guided bone regeneration in horizontal bone atrophy are both predictable therapeutic options.

Mental Health Risk and Protective Factors of Nigerian Male Asylum Seekers Hosted in Southern Italy: a Culturally Sensitive Quantitative Investigation.

This study provides a culturally sensitive quantitative investigation aimed at assessing the post-traumatic symptomatology, post-migratory difficulties, and resilience of 36 Nigerian male asylum seekers hosted in the province of Caserta, South Italy. A survey composed by the Harvard Trauma Questionnaire-Revised (HTQ-R), the Post-Migratory Checklist (PLMD), and the Connor-Davidson Resilience Scale (CD-RISC) was administered to participants. Descriptive and correlation analyses were made in order to describe the mental health risk and protective factors and understand the relation between these. A linear regression analysis was used to evaluate the influence of post-migratory difficulties and resilience on PTSD. Stratified bivariate analyses were also computed to detect PTSD group and no-PTSD group differences about post-migration difficulties and resilience levels. Regression analysis showed that PMLD numbers significantly increased the risk of having PTSD. No significant effect emerged for the level of resilience. Statistically significant differences between the PTSD group and non-PTSD group in relation to post-migratory difficulties were also found. No differences in the resilience factors emerged. The results offer a glimpse into a specific ethnic group of asylum seekers and its mental health risks and protective factors, taking into consideration the specificities of their past and current life-story experiences. Clinical implications for professionals working in the field of forced migration will be outlined.

The Role of Emotion Regulation as a Potential Mediator between Secondary Traumatic Stress, Burnout, and Compassion Satisfaction in Professionals Working in the Forced Migration Field.

BACKGROUND: Professionals working with refugees are vicariously exposed to complex traumatic experiences lived by forced migrants, which can lead to the risk of developing secondary traumatic stress, burnout, and a poor compassion satisfaction. The current study aimed to explore the effects of secondary traumatic stress on burnout and compassion satisfaction in 264 Italian professionals working with refugees and forced migrants. Moreover, it examined the mediating role of emotion regulation between secondary traumatic stress and both burnout and compassion satisfaction. METHODS: A structural equation modeling (SEM) was performed to test the hypothesis. RESULTS: The results showed that increased levels of secondary traumatic stress were associated with an increase of burnout both directly and indirectly through the mediation of emotion regulation. Emotion regulation also totally mediated the relationship between secondary traumatic stress and compassion satisfaction. CONCLUSIONS: The results suggested that prevention or interventions programs targeting emotion regulation might be important to improve the professional quality of life of operators working with refugees and forced migrants.

The Effect of Diabetes and Hyperglycemia on Horizontal Guided Bone Regeneration: A Clinical Prospective Analysis.

Guided bone regeneration (GBR) is a reconstructive procedure for treating atrophic alveolar ridges. This study aims to assess the correlation between different glycemic control levels and clinical findings in patients undergoing horizontal GBR before implant placement. The study population consisted of all patients requiring horizontal GBR. Patients were divided into three groups based on HbA1c levels: non-diabetic normoglycemic patients (HbA1c < 5.7%), non-diabetic hyperglycaemic patients (HbA1c < 6.5%), and patients with controlled diabetes (HbA1c < 7%). The primary outcomes were the horizontal (mm) and vertical (mm) dimensional changes of the alveolar ridge 6 months after the procedure. The study sample consisted of 54 patients. Sixty-eight implants (95.8%) were classified as "successful," meaning the possibility of inserting a standard-sized implant following the GBR (diameter ≥ 4 mm). There was a statistically significant difference between the three groups in terms of horizontal gain at 6 months: in particular, there was a statistically significant difference between group 1 and group 2 (p = 0.026) and between group 1 and group 3 (p = 0.030). The present investigation showed that patients with HbA1c levels below 7% could undergo GBR and obtain a statistically significant horizontal bone gain.

The Effect of Hyperlipidemia on Peri-implant Health: A Clinical and Radiographical Prospective Study.

High levels of cholesterol and triglycerides may have a negative effect on the immune system and bone health, leading to lower bone mineral density, an increased risk of osteoporosis, and bone fractures, and could therefore also be related to a significant worsening of peri-implant health. The purpose of the following study was to evaluate whether the altered lipid profile in patients who undergo implant insertion surgery represents a prognostic factor capable of influencing clinical outcomes. This prospective observational study was conducted on 93 subjects; patients were required to have taken blood tests to obtain triglycerides (TG), total cholesterol, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) levels prior to the surgical procedure to classify them according to current American Heart Association guidelines. The outcomes considered were marginal bone loss (MBL) 3 years after implant placement, full-mouth plaque score (FMPS), and full-mouth bleeding score (FMBS) 3 years after surgery. A statistically significant correlation was found between hypertriglyceridemia and MBL as well as between total cholesterol and MBL. There is no statistically significant correlation between the variables analyzed and the secondary outcomes 3 years after implant placement. Peri-implant marginal bone loss may be influenced by hyperlipidemia. However, further studies are needed, with larger samples and more extensive follow-ups, to confirm these results.

From struggle to hope: A gender-sensitive investigation on Nigerian male and female asylum seekers' experiences.

The study presents a qualitative and culturally-sensitive investigation of the lived experiences of the forced migration of six Nigerian asylum seekers, three men and three women, hosted in Italy. Through a focus on gender identity issues, the study aimed to explore possible gender differences between participants and define their specific needs, requirements and characteristics. Overall, the gender-focused perspective through which we explored participants' subjective experiences has enriched our understanding of their unique life stories, shedding light on the psychic dimensions as well as on the social and cultural inscriptions of their gender identity and providing insights on the different ways in which Nigerian women and men made sense of their experiences of displacement, migration, violence and trauma.

Italian Validation of AAS-R: Assessing Psychometric Properties of Adult Attachment Scale-Revised in the Italian Context.

The Adult Attachment Scale-Revised (Collins and Read in J Person Soc Psychol 58(4):644, 1990. https://doi.org/10.1037/0022-3514.58.4.644) measures the dimensions of the attachment style of adults through the degree to which the individual feels comfortable in intimacy and closeness with the partner (Close), with dependence on the partner (Depend) and worrying about being rejected or unloved (Anxiety). Dimensions measured by the AAS can capture the core of the structure that determines adults' differences in attachment styles. This study aimed to evaluate the factorial structure of the AAS-R among a sample of Italian adults. The Italian translation of AAS-R was administered to the sample of 1546 Italian adults (M = 27.4; SD 9.35). Exploratory factor analysis and confirmatory factor analysis were performed to examine the validity of the Italian version of the AAS-R measure. The present study showed that the Italian version of the AAS-R has a clear factorial structure and good psychometric properties. Clinical and research implications were discussed.

Migrant women and gender-based violence: Focus group with operators.

Gender violence is the most important factor that leads women refugees and asylum seekers to leave their country and is one of the main risks to which the migration journey exposes them. To the multidimensional trauma of migration is added the complex trauma of gender violence making migrant women even more vulnerable. This study, aimed to investigate meanings of experience of the operators who deal with migrant women in Southern Italy. For the purpose of the study, we use the Focus Group, for data collection and the Interpretative Phenomenological Analysis (IPA) to analyze the data. The study confirms the need to structure specific paths for the well-being of forced migrant women victims of violence that respect gender dynamics and cultural differences. In particular, in the context of the transcultural clinic, it will be demonstrated that focus groups are a useful resource and propose the construction of "métissée" spaces.

'Isolated together': online group treatments during the COVID-19 pandemic. A systematic review.

Considering the emerging need to face the negative impact of the pandemic on mental health, social support, and access to health services, it became a critical issue to adapt to online group settings and create new group interventions to face the developing distress during this time. The aim of the current study is to investigate the main findings on OPGI conducted during the COVID-19 pandemic from March 2020 until March 2022, with a particular focus on: i) the therapeutic group factors; ii) what kind of OPGI works and for whom; iii) settings and emerging dimensions. In accordance with PRISMA guidelines, we performed a systematic review on scientific databases (PsychINFO, PubMed, Web of Science and EBSCO) searching for studies published between March 2020 and March 2022. 'Group intervention' or 'group therapy' or 'group treatment' crossed with 'COVID-19' and synonymous, were used as keywords. Internet based intervention was used as an eligibility criteria during the full-text screening. A total of 1326 articles were identified, of which 24 met the inclusion criteria. Among all studies, with different participants and different orientations, data extracted supported psychological online group interventions as an effective approach to reducing psychological distress and increasing psychological resources in the interpersonal field. Our findings also showed that COVID-19 has led to new needs and issues, that require the investigation of new dimensions for online psychological interventions. Methodological and clinical implications will be discussed through a descriptive table related to setting characteristics. Recommendations are made for future research.

Implant Placement with Simultaneous Guided Bone Regeneration Using Advanced Platelet-Rich Fibrin and a Deproteinized Bovine Bone Mineral: A 2-Year Retrospective and Comparative Study.

A lack of bone volume may compromise a correct three-dimensional implant placement. This study was designed to evaluate the clinical and radiographic outcomes of simultaneous horizontal guided bone regeneration (GBR) performed using autogenous bone or blood-derived products mixed with a bone xenograft. The study population consisted of patients operated on using one of two clinical protocols for GBR: group A, which used autogenous bone mixed with a bone xenograft, and group B, which used advanced platelet-rich fibrin (A-PRF) mixed with a bone xenograft. The primary outcome was the clinical gain in the peri-implant defect. The secondary outcomes included an analysis of the postoperative healing, periodontal parameters, marginal bone loss, and occurrence of adverse events. All of the surgeries were carried out successfully. One patient in each group experienced a case of early implant loss, and three patients (one in group A and two in group B) presented biologic complications. The mean peri-implant vertical defect heights at baseline in group A and group B were 3.6 ± 0.9 mm and 4 ± 1.5 mm, respectively (P = .382). No statistically significant differences in the mean residual defect heights (P = .521) or in the postoperative wound healing (P = .611) were observed. Stable peri-implant marginal bone levels were recorded after loading in both groups. The use of A-PRF combined with a particulate bone xenograft and covered with a fixed collagen membrane may provide clinical results similar to those obtained via autogenous bone mixed with bone xenograft.

Psychometric properties of the Sleep Hygiene Index in a large Italian community sample.

OBJECTIVE/BACKGROUND: Poor sleep hygiene is considered an exacerbating and perpetuating factor of sleep disturbances and is also associated with poor mental health. The Sleep Hygiene Index (SHI) is a self-report measure assessing adherence to sleep hygiene practices. The aim of this study was to estimate the psychometric properties of the SHI in an Italian representative sample of the general population, following a formative measurement approach. PATIENTS/METHODS: Participants (n = 6276; M = 33.62, SD = 13.45) completed the SHI alongside measures of sleep disturbance, depression, anxiety, and stress. To consider the item formative nature, sets of item-composites weighted by means of canonical correlation analysis was created and a confirmatory factor analysis (CFA) was implemented. Factorial invariance tests were computed considering both presence of sleep problems and presence of emotional distress symptoms as grouping variables. RESULTS AND CONCLUSIONS: CFA confirmed the unidimensional structure of SHI. Internal consistency was acceptable (ω = 0.752). Test-retest reliability at 8-10 months presented an ICC of 0.666. SHI significantly correlated with sleep, depression, anxiety and stress symptoms (r range from 0.358 to 0.500). Configural and metric invariance were reached for both grouping variables. Partial scalar invariance was obtained only across emotional distress groups. People with emotional symptoms reported higher latent means on the sleep hygiene dimension. Findings support the validity and reliability of the Italian version of the SHI. Importantly, the SHI showed robust psychometric properties both in healthy individuals and in individual reporting mental health symptoms. Thus, it is advisable to use this version of the SHI in both research and clinical practice.

The Effect of Controlled Diabetes and Hyperglycemia on Implant Placement with Simultaneous Horizontal Guided Bone Regeneration: A Clinical Retrospective Analysis.

Diabetes represents a challenge in implant therapy because hyperglycemia may negatively affect bone regeneration, directly compromising clinical outcomes and increasing clinical failures. The aim of this retrospective study is to analyse the prognostic significance of HbA1c levels in patients undergoing implant placement associated with horizontal guided bone regeneration. Thirty-four patients were divided into 3 groups according to their HbA1c levels: nondiabetic normoglycemic patients (HbA1c < 5.7%), nondiabetic hyperglycemic patients (HbA1c < 6.5%), and controlled diabetic patients (HbA1c < 7%). Primary outcomes were dimensional changes in height (VDH) and width (DW) of the peri-implant defect. Secondary outcomes were evaluations of periodontal parameters of adjacent tooth sites, wound healing, marginal bone loss (MBL), and survival and success rates. At T 1 (6 months), mean VDH values in groups 1, 2, and 3 were, respectively, 0.07, 0.5, and 0.25 mm. Mean DW values in those same groups were, respectively, 0.07, 0.38, and 0.33 mm. HbA1c levels were not statistically related to VDH and DW values at T 1. No statistically significant differences were observed in MBL between groups (p = 0.230). Implant survival and success rates were, respectively, 98% and 96%. Simultaneous guided bone regeneration is a feasible procedure for the treatment of horizontal bone deficiencies in controlled diabetic patients.
