“…Esposito et al's study in 1993 found a strong correlation between bone loss on adjacent teeth and tooth to implant distance in single tooth Branemark external hex implants 36 . One of the most common problems after ITRT is that the interdental papilla loses height and volume especially at the distal aspect due largely in part to physiologic process of alveolar ridge remodeling following tooth extraction 10,37–39 . The additional space offered by this narrow coronal body design increases the distance between the implant body and adjacent tooth attachment apparatus, thus enabling maintenance of the interproximal bony peak and the contours of the overlying papilla 40…”

“…The distal papilla often exhibits a more atrophic appearance in both the vertical and horizontal dimensions. 10 This is due to the physiologic process of alveolar ridge remodeling following tooth extraction, local anatomic factors such as the position and configuration of the cementoenamel junction, and the nature of immediate implant placement relative to the socket morphology. A macrohybrid design incorporating a prosthetic angle correction and body-shift feature in a singular form (Inverta Co-axis ® , Southern Implants, Pty., RSA) (INV) was introduced in 2018 to overcome these dilemmas.…”

“…Wider diameter implants are effective in achieving adequate primary stability in ITRT, but their design inherently decreases the distance between the fixture and the facial gap and interproximal bony crest. Moreover, they can pose the potential risk of apical fenestration of the extraction socket when aiming the prosthetic screw channel to the cingulum 10,13–15 …”

“…8,9 In addition, loss of interdental papilla height and volume has been illustrated as another esthetic dilemma, which is the result of inadequate proximity to an adjacent natural tooth and preexisting anatomic factors. 10 Ideal labial bone plate thickness of 2.0 mm and tooth-to-implant distance of 1.5 mm have been suggested for the long-term stability of ridge contour and the interproximal bony peak. 11,12 While smaller diameter implants are recommended to maintain the distances between implant body to the labial bone plate and between adjacent teeth at the crest, achieving adequate primary stability with these fixtures can be a clinical challenge.…”

The concept of immediate tooth replacement therapy (ITRT) in the esthetic zone has become a viable treatment modality and widely accepted in clinical practice. However, achieving adequate primary stability that enables immediate provisional restoration and desirable space for bone‐grafting with conventional tapered body implant designs is challenging. The macro‐hybrid implant design with a prosthetic angle correction and body‐shift feature in a singular form provides not only greater primary stability of a wider diameter implant but also circumferential gap distance both facially and interproximally preserve the labial bone plate and interdental attachment apparatus of the adjacent natural teeth thereby maintaining the interdental papilla. The present clinical series exemplifies the clinical advantages of this inverted body‐shift implant design in ITRT in various clinical scenarios in (1) single tooth replacement in a Type 1 intact socket with a thin periodontal phenotype, (2) single tooth replacement in a Type 2 socket with a dentoalveolar dehiscence of the labial bone plate, and (3) multiple adjacent teeth replacement of two maxillary central incisor. Clinical significance The macro‐hybrid design implant with a prosthetic angle correction and body‐shift feature in a singular form provides greater midfacial gap distance as well as tooth‐to‐implant distance to preserve the interdental attachment of the adjacent natural teeth thereby leaving the interdental papilla undisturbed, without sacrificing higher primary stability afforded by larger diameter implants.

Background There is limited information on the need for bone augmentation in the context of delayed implant placement whether alveolar ridge preservation (ARP) is previously performed or not. The primary aim of this retrospective cohort study was to evaluate the efficacy of ARP therapy after tooth extraction compared with unassisted socket healing (USH) in reducing the need for ancillary bone augmentation before or at the time of implant placement. Methods Adult subjects that underwent non‐molar single tooth extraction with or without simultaneous ARP therapy were included in this study. Cone beam computed tomography scans obtained before tooth extraction and after a variable healing period were used to record the baseline facial bone thickness and to virtually plan implant placement according to a standard method. A logistic regression model was used to evaluate the effect of facial alveolar bone thickness upon tooth extraction and baseline therapy (USH or ARP) on the need for additional bone augmentation, adjusting for several covariates (i.e., age, sex, baseline KMW, and tooth type). Results One hundred and forty subjects that were equally distributed between both baseline therapy groups constituted the study population. Implant placement was deemed virtually feasible in all study sites. Simultaneous bone augmentation was considered necessary in 60% and 11.4% of the sites in the USH and ARP group, respectively. Most of these sites (64.2% in the USH group and 87.5% in the ARP group) exhibited a thin facial bone phenotype (<1 mm) at baseline. Logistic regression revealed that the odds of not needing ancillary bone augmentation were 17.8 times higher in sites that received ARP therapy. Furthermore, the need for additional bone augmentation was reduced 7.7 times for every 1 mm increase in facial bone thickness, regardless of baseline therapy. Conclusions Based on a digital analysis, ARP therapy, compared with USH, and thick facial alveolar bone largely reduce the need for ancillary bone augmentation at the time of implant placement in non‐molar sites.

Aim: To assess radiographic, restorative, clinical and technical outcomes as well as patient satisfaction of directly veneered zirconia restorations cemented on non-original titanium bases over 5 years. Material and Methods:Twenty-four patients with a single missing tooth in the aesthetic zone were recruited. All patients received a two-piece implant with a screwretained veneered zirconia restoration cemented extraorally on a titanium base abutment. Marginal bone levels (MBL), marginal bone changes, technical complications, patient satisfaction and clinical parameters including probing depth, bleeding on probing and plaque index were assessed at crown delivery (baseline), at 1 year (FU-1) and 5 years (FU-5) of follow-up. To investigate the relationship between restorative angle and MBL as well as marginal bone changes (bone loss/bone gain), correlation tests and linear regression models were carried out.Results: Twenty-two patients were available for re-examination at 5 years. The mean MBL amounted to 0.54 ± 0.39 mm at baseline, and to 0.24 ± 0.35 at FU-5 (=bone gain) (p < .001). At FU-1, a positive correlation (r = .5) between the mesial restorative angle and mesial MBL was found (p = .012). Marginal bone changes between baseline and FU-1 at mesial sites were also positively correlated with the mesial restorative angle (r = .5; p = .037). Linear and logistic regression models confirmed that mesial marginal bone loss was significantly associated with the mesial restorative angle at FU-1 (p < .05). At 5 years, these significant associations at mesial sites disappeared (p > .05).At distal sites, no correlations or associations between the restorative angle and MBL or marginal bone changes were found regardless of the time point. During the 5-year follow-up, 5 technical complications occurred, mainly within the first year and mostly chippings. All patients were entirely satisfied with their implant-supported restoration at 5 years.
