Comparison of the stability of immediate dental implant placement in fresh molar extraction sockets in the maxilla and mandible: a controlled, prospective, non-randomized clinical trial.

The aim of this study was to assess the stability of immediate dental implants in fresh molar extraction sockets and to compare those placed in the maxilla and mandible. This was a controlled, prospective, non-randomized clinical trial; the maxilla was the test group and the mandible was the control group. Thirty patients with an unrestorable molar tooth who needed immediate implant placement were included. The implant surgery was performed using a surgical stent and a guided surgery kit. After placement of the implant, the implant stability quotient (ISQ) was measured. A titanium customized healing abutment was inserted, and further ISQ values were obtained during 24 weeks of follow-up. The mean primary stability after immediate implant placement was >70 (73.98 ± 5.40 in the maxilla and 73.59 ± 6.74 in the mandible; P = 0.864). In the maxilla, stability was reduced at 2 weeks and 4 weeks and then increased gradually. In conclusion, immediate implant placement in the molar region with computer-guided surgery resulted in excellent implant stability. Higher mean ISQ values were obtained for the implants in the mandibular molar region when compared to the maxillary molar region (significant at 24 weeks, P = 0.018).

Effect of soft tissue volume on midfacial gingival margin alterations following immediate implant placement in the esthetic zone: a 1-year randomized clinical and volumetric trial.

The current trial evaluated the midfacial gingival margin changes, volumetric, radiographic and clinical alterations 1-year following immediate implant placement with customized healing abutment (IIP + CHA) either solely, or in combination with xenograft (IIP + Bonegraft) or with connective tissue grafting (IIP + CTG) at sites with thin labial bone in the esthetic zone. Thirty-nine non-restorable maxillary teeth indicated for extraction in the esthetic zone were included. Participants were randomly assigned into three equal group; IIP + Bonegraft (Control), IIP + CTG and IIP + CHA. Midfacial gingival margin changes(mm) as primary outcome, labial soft tissue contour change(mm), interdental tissue height changes and total volume(mm3) were assessed. Amount of bone labial to the implant and crestal bone level changes were also recorded. All outcomes were measured 1-year post-operative. The midfacial gingival margin changes demonstrated a significant difference (P ≤ 0.05) between the groups showing -0.98, -0.74 and -1.54mm in sites treated with IIP + Bone graft, IIP + CTG and IIP + CHA respectively after1-year. While labial soft tissue contour change (mm), total volume (mm3) and distal interdental tissue height changes (mm) revealed a significant difference after one-year between the studied groups, yet mesial interdental tissue height changes showed no difference (P > 0.05). Both IIP + Bone graft and IIP + CHA groups revealed a significant positive correlation between the total volume loss (mm3) after 1 year and mid-facial gingival margin changes (P ≤ 0.05). However, no significant correlation was observed in the IIP + CTG group (P = 0.63). CBCT measurements showed a significant difference in crestal bone changes between the three groups (P ≤ 0.05), yet, there was no significant difference regarding mean amount of bone labial to the implant(P > 0.05). This investigation suggests that the mere presence of CTG simultaneous with IIP in the anterior maxilla reduced the midfacial gingival margin alterations (mm), besides, CTG decreased the overall volume loss (mm3) by 5-folds compared to the other studied groups after one year. Meanwhile, using CHA alone with IIP failed to maintain the peri-implant soft tissues contour. The current trial was retrospectively registered at Clinical trials.gov (ID: NCT05975515, Date: 27-July-2023).

Preformed customized healing abutments in a biologically oriented preparation technique procedure: a 3-year retrospective case-control study.

The objective of the present study was to determine the 3-year clinical and dimensional soft tissue change following implant placement in healed sites before and after loading with either customized or conventional healing abutments. Premolar/molar implants were immediately loaded with either provisional and customized abutments without finishing lines according to the principles of the biologically oriented preparation technique (BOPT; test group) or conventional healing abutments (control group). Three months later, the definitive crowns were fabricated. Primary outcomes (soft tissue changes) and secondary outcomes (adverse events) were registered. A total of 50 of the 87 subjects who were originally included were finally selected for the present retrospective analysis: 23 in the test group and 27 in the control group. During the first days after surgery, two adverse events of mucositis occurred, one in each group. A few technical complications were recorded such as the unscrewing of four screw-retained crowns. A significant increase in the alveolar width was observed in both groups (test: +2.5 ± 0.5 mm; control: +1.0 ± 0.9 mm). The widths appeared unchanged from 3 months to 3 years in both groups. There were no significant differences regarding the width of the keratinized mucosa measured at baseline and after follow-up. The Jemt papilla index showed a higher increase in the test group compared with the control group. Within the 3-year follow-up period, the peri-implant soft tissue outcomes of single, immediately loaded implants with customized healing abutments showed better results in terms of thickness and width compared with those of the conventional group. The number of side effects (mucositis and dehiscence) appeared to be very similar for both groups. In addition, customized healing abutments led to significant augmentation of the alveolar width, which was more than twice of that registered in the conventional group.

Wide Restorative Emergence Angle Increases Marginal Bone Loss and Impairs Integrity of the Junctional Epithelium of the Implant Supracrestal Complex: APreclinical Study.

To assess the influence of the emergence angle on marginal bone loss (MBL) and supracrestal soft tissue around dental implants. In six mongrel dogs, the mandibular premolars and molars were extracted. After 3 months of healing, four dental implants were placed in each hemimandible. The implants were randomly allocated to receive one of four customized healing abutments, each with a different value of the restorative emergence angle: 20°, 40°, 60° or 80°. Intra-oral radiographs were taken after placing the healing abutments and at 6, 9, 16 and 24 weeks of follow-up. Then, micro-CT and undecalcified histology and synchrotron were performed. MBL over time was analysed with generalized estimating equations (GEEs) and adjusted for baseline soft-tissue thickness. From implant placement to 24 weeks, GEE modelling showed that the MBL at mesial and distal sites consistently increased over time, indicating MBL in all groups (p < 0.001). The model indicated that MBL varied significantly across the different restorative angles (angle effect, p < 0.001), with 80° showing the greatest bone loss. Micro-CT, histology and synchrotron confirmed the corresponding trends and showed that wide restorative angles (60° and 80°) impaired the integrity of the junctional epithelium of the supracrestal tissue. A wide restorative angle increases MBL and impairs the integrity of the junctional epithelium of the implant supracrestal complex.

Comparative Evaluation of Soft Tissue Reaction to Titanium and Polyetheretherketone Customized Healing Abutments: a Split-Mouth Randomised Clinical Trial

Aim. This study aimed to evaluate the peri-implant soft tissue response to customized healing abutments (CHAs) made of titanium and polyetheretherketone (PEEK). Methods. Titanium and PEEK CHAs were mounted on bone-level dental implants in bilateral edentulous patients in a randomized split-mouth study design. After a three-week healing period, the clinical parameters of the peri-implant soft tissues were assessed. The value of marginal bone resorption was measured by cone-beam computed tomography. In addition, peri-implant crevicular fluid samples were obtained to identify periodontal pathogenic bacteria, cytokine levels, and active neutrophil collagenase (aMMP-8) concentration. Microcirculation and oxygenation parameters were assessed using laser Doppler flowmetry and optical tissue oximetry. In addition, wavelet analysis was conducted to study blood flow control mechanisms. Results. Out of the 23 participants initially recruited, 20 were assessed after titanium and PEEK CHA installation due to losses to follow-up. The peri-implant soft tissue around 27 titanium and 25 PEEK CHAs was evaluated during follow-ups. No differences were found in the values of marginal bone resorption, cytokine levels, or total bacterial load (p&gt;0.05). PEEK CHAs demonstrated lower bleeding on probing values, less plaque accumulation, and faster relief of ischemia and hypoxia. Although aMMP-8 concentration was higher in the PEEK group, the values were within normal limits. Conclusions. The results of this comparative study showed a positive soft tissue response to PEEK CHAs. However, further studies comparing the effectiveness of different materials for CHAs should be carried out, considering their specific physical properties and processing protocols.

Soft-Tissue Management Dental Implants with Digitally Customized Healing Abutments: A Pilot Study

Background: This pilot study aimed to evaluate the effectiveness of digitally crafted customized healing abutments in stabilizing peri-implant soft tissues following tooth extraction and assess the preservation of peri-implant soft tissue architecture over 5 years. Material and Methods: Forty patients (age ≥ 25 years) were divided into test (n = 20) and control (n = 20) groups. The test group received dental implants with immediate loading after tooth extraction, along with customized healing abutments fabricated using CAD/CAM technology. The control group received dental implants with immediate loading without customized healing abutments. The primary outcome was the change in distance between the peri-implant soft tissue margin and implant fixture surface from baseline to 5 years post implantation. Results: In the test group, there was a significant decrease in the distance between the peri-implant soft tissue margin and fixture surface from baseline to 5 years (p &lt; 0.001), with pairwise comparisons showing significant differences between multiple time points (p &lt; 0.05). The control group showed less pronounced changes over time. Conclusions: Within the limitations of this pilot study, digitally fabricated customized healing abutments appear effective in stabilizing peri-implant soft tissues and preserving soft tissue architecture around dental implants over 5 years following immediate implant placement. Randomized controlled trials are needed to confirm these findings.

Effect of Customized and Prefabricated Healing Abutments on Peri-Implant Soft Tissue and Bone in Immediate Implant Sites: A Randomized Controlled Trial

This study aimed to evaluate the effect of customized healing abutments compared to prefabricated healing abutments in immediate implant sites. Twelve patients requiring single immediate implant placement were divided into two groups: a prefabricated group received prefabricated titanium healing abutments, and a customized group received a polyetheretherketone (PEEK) customized healing abutments fabricated based on the individuals’ digital impressions. Outcomes, including peri-implant horizontal and vertical soft tissue alteration, bone level change, volume change, pain score, and pink esthetic score (PES) change, were evaluated at the 1-, 4-, and 6-month follow-ups compared to pre-extraction teeth. At the 1- and 4-month follow-ups, the customized group had a significantly lower buccal volume variation (BVv). At the 6-month follow-up, neither group showed any significant difference in the marginal bone change; however, the customized group had a significantly lower PES change and a lower pain score. In the anterior and premolar regions, the customized group showed the preservation of peri-implant buccal horizontal soft tissue and buccal volume, while in the molar regions, the preservation of papilla height and midfacial height was observed. The morphology of the customized healing abutment demonstrated a better trend in preservation of peri-implant soft tissue, esthetic outcomes, and lower patient discomfort in immediate implant sites.

Sealing socket with custom healing abutment in case of immediate posterior implant placement: A case report

Replacing a hopeless molar with a dental implant is one of the most common treatment modalities in implant dentistry. However, immediate implant post-extraction in the posterior region requires managing the bone gap and ensuring primary closure of the socket. To address this anatomical consideration, several authors have proposed using a custom abutment to seal the socket after immediate implant placement, maintain soft tissue contour, and stabilize the surrounding tissues. For example, the “Sealing Socket Abutment” (SSA) enhances the anatomical emergence profile, which facilitates the biological, prosthetic, and aesthetic integration of the future supra-implant prosthesis. A 32-year-old female patient in good general health consulted the Outpatient and Implantology Department of the dental clinic in Monastir, Tunisia, for the extraction of the root tip of the left first mandibular molar (tooth number 36) and subsequent implant rehabilitation. The patient’s medical history was unremarkable, with no known allergies, or chronic conditions. Follow-up appointments were scheduled to monitor the healing process and ensure successful integration of the implant. The aim of this paper is to present, through this clinical case report, the SSA abutment fabrication protocol using the direct technique and to discuss the advantages and limitations of this technique.

Immediate Implant and Customized Healing Abutment Promotes Tissues Regeneration: a 5-year Clinical Report.

Significant alveolar bone resorption follows tooth extraction. Immediate implant placement alone is not sufficient to prevent this phenomenon. In this clinical case, a fractured upper first premolar was replaced by an immediate implant and a customized healing abutment designed on the perimeter of the extractive alveolus. After 3 months, the implant was restored. The facial and interdental soft tissue was maintained with appreciable success after 5 years. The pre- and 5-year-post-treatment CT scans showed no bone loss. The use of an interim customized healing abutment helps preventing hard and soft tissues collapse. This technique is very straightforward and might represent a smart preservation strategy when there is no indication for adjunctive hard or soft tissue grafting.

Peri-implant Outcomes from Customized Healing Abutments Using Immediate Implants: A Systematic Review.

To evaluate the peri-implant outcomes of customized healing abutments (CstHA) placed on dental implants inserted in fresh tooth extraction sockets. The study was registered on PROSPERO: CRD42022304320. A systematic search in PubMed, Scopus, and Web of Science was conducted between April 2022 and October 2022 to identify clinical studies involving immediate implant surgery associated with CstHA placement. The Joanna Briggs Institute Critical Appraisal and RoB2 tool were performed for the risk of bias analysis. A total of 12 studies were included, most of them with low risk of bias. Four studies compared CstHA vs conventional healing abutments (CnvtHA), two compared CstHA vs cover screw and collagen matrix (CMa), and six were clinical case series. For the CstHA vs CnvtHA comparison, favorable results were observed for CstHA considering papilla maintenance and probing depth, yet the mean marginal bone level was statistically similar between CstHA and CnvtHA. CstHA showed advantages when compared to CMa for total bone volume, papilla height, and midfacial mucosa maintenance. Significantly less horizonal bone loss was reported when using CstHA compared with CMa. Horizontal and vertical bone loss was observed in a few (or no) sites in the case series using CstHA. CstHA provides favorable peri-implant response because in general it does not result in a significant loss of soft and hard tissues.

Modified Periosteal Inhibition (MPI) Technique for Immediate Implants: A Multi-Center Retrospective Case Series Study

Background: Alveolar socket preservation is a topic of serious interest, and researchers have investigated this problem quite extensively. In terms of aesthetics, it is very important to avoid bone resorption if the clinician decides to insert the implant immediately after the extraction. Recently, a new approach utilizing a barrier external to the socket has been developed, which has advanced the evolution of this technique. Immediate implants have also created some difficulty when re-evaluated in long-term follow-up, especially when an aesthetic result is part of the goal of the procedure. Methods: The modified periosteal inhibition (MPI) technique, which has shown interesting outcomes, is evaluated in this paper on a large group of patients. In this case series, among 14 patients, 11 received immediate implants using the MPI technique and immediate provisionalization, and 3 received immediate implants using the MPI technique and customized healing abutment. All patients showed ridge preservation to different degrees, ranging from 0.02 to 1.17 mm, with an average gain of 0.51 mm. Results: all of the 14 patients maintained the original ridge shape, and 1 showed an increase in bucco-lingual size. Conclusions: This case series confirms the promising information reported in earlier studies on this technique. Larger samples will be necessary to confirm the predictability of this new approach.

Efficacy of Socket Shield Technique for Immediate Implant Placement in Maxillary Anterior Region – A Case Series with Review.

&#x0D; &#x0D; The socket-shield technique is the most crucial treatment modality for esthetic enhancement and ridge preservation technique but it has been less discussed and documented. This case series describes the placement of implants immediately following extraction of a non-restorable which are all fractured and hopeless maxillary teeth and using this technique and functional and esthetic outcomes of the treatment was a successful event.&#x0D; In this review, immediate implant were placed using socket shield protocol to treat ten patients with non-restorable teeth. Dissection was performed along the long axis of the roots in a mesiodistal direction; and atraumatically the buccal fragment of the root was left attached to the bone while the palatal fragment was extracted. Implants were placed after sequential osteotomy drilling. A customized healing abutment was fabricated chairside to create an emergence profile. During the prosthetic phase, patients had follow-up visits after 4 weeks and after 6 months. The definitive prosthesis was cemented using a cement-retained porcelain fused to metal.&#x0D; &#x0D;

Volumetric analysis on the use of customized healing abutments with or without connective tissue graft at flapless maxillary immediate implant placement: A randomized clinical trial.

To evaluate buccal volume change after using a customized healing abutment with or without connective tissue grafts (CTG) in flapless maxillary immediate implant placement (IIP). The present study was designed as a randomized clinical trial (RCT). Patients treated with flapless maxillary IIP were allocated into two groups, both receiving a customized healing abutment, and additionally, the test group received a CTG. A cone-beam computerized tomography (CBCT) allowed to access the initial buccal bone thickness (BT). Digital impressions were taken prior to extractions (T0), 1 month (T1), 4 months (T2), and 12 months (T3) after implant insertion and superimposed with computer software allowing to compute variables related to buccal volume variation (BVv) and total volume variation (TVv) (ClinicalTrials.gov: NCT05060055). Thirty-two patients (mean age 48 ± 11 years), sixteen in each group, were evaluated after a 12-month period. After 1 year of treatment, no significant differences were found between groups, although in participants with BT ≤1 mm, control and test groups showed a BVv of -14.18 ± 3.49% and -8.30 ± 3.78%, respectively (p = .033). Regarding mucosa height variation variables, the control group showed approximately the triple vertical recession in both papillae. The placement of a CTG was not capable of completely maintaining the initial peri-implant tissue architecture, although in thin-bone phenotypes, less dimensional changes are expected when a CTG was used.

Impact on peri-implant connective tissue of laser treated versus traditional healing abutments: a human clinical trials

BackgroundDental implant is the principal treatment for edentulism and the healthiness of the peri-implant tissue has a pivotal role for its longterm success. In addition, it has been shown that also the topography of the healing abutment can influence the outcome of the restoration. The objective of this human clinical trial was to assess the impact of a novel laser-treated healing abutment on peri-implant connective tissue and extracellular matrix proteins compared to the conventional machined surface, which served as the control group.MethodsDuring second surgical stage a customized healing abutment were inserted on 30 single dental implants. Healing abutments were realized with two alternated different surface (two side laser-treated surfaces and two side machined surfaces) in order to be considered both as test and control on the same implant and reduce positioning bias. Following the soft tissue healing period (30 ± 7 days) a 5 mm circular biopsy was retrieved. Immuno-histochemical and quantitative real-time PCR (qPCR) analyses were performed on Collagen, Tenascin C, Fibrillin I, Metalloproteinases (MMPs) and their inhibitor (TIMPs). 15 were processed for qPCR, while the other 15 were processed for immunohistochemical analysis. Paired t-test between the two groups were performed. A value of p < 0.05 was considered statistically significant.ResultsResults revealed that the connective tissue facing the laser-treated surface expressed statistically significant lower amount of MMPs (p < 0.05) and higher level of TIMPs 3 (p < 0.05), compared to the tissue surrounding the machined implant, which, in turn expressed also altered level of extracellular matrix protein (Tenascin C, Fibrillin I (p < 0.05)) and Collagen V, that are known to be altered also in peri-implantitis.ConclusionsIn conclusion, the laser-treated surface holds promise in positively influencing wound healing of peri-implant connective tissue. Results demonstrated that topographic nature of the healing abutments can positively influence mucosal wound healing and molecular expression. Previous studies have been demonstrated how laser treatment can rightly influence integrity and functionality of the gingiva epithelium and cell adhesion. Regarding connective tissue different molecular expression demonstrated a different inflammatory pattern between laser treated or machined surfaces where laser treated showed better response. Targeted interventions and preventive measures on peri- implant topography could effectively minimize the risk of peri-implant diseases contributing to the long-term success and durability of restoration. However, new studies are mandatory to better understand this phenomenon and the role of this surface in the peri-implantitis process. Trial registrationThis trial is registered with ClinicalTrials.gov Identifier: (Registration Number: NCT05754970). Registered 06/03/2023, retrospectively registered.

Alternative soft tissue management techniques in posterior region of immediate implant

Management of soft tissues in posterior region after immediate implant placement is a treatment widely performed in the dentists’ clinical practice. However, due to many particularities of this kind of treatment it is still considered a great challenge. Objective: In this way, the aim of this paper is to report three cases that describe an alternative and simpler direct technique of customized immediate posterior healing abutment after immediate implant placement. Case report: The cases were performed using an alternative technique of customized immediate posterior healing abutment, which aims to guide the peri-implant tissue healing, preserving the anatomic emergence form and avoiding the need of a second surgery. Conclusion: We could observe that customized healing abutments assist in tissue stability, facilitate hygiene during the healing period, reduce the number of surgery steps, reduce the amount of consultations for tissue conditioning and it is a more cost-effective treatment for the patient and professional.

Immediate Implant and Customized Healing Abutment for a Periodontally Compromised Socket: 1-Year Follow-Up Retrospective Evaluation.

Immediate dental implant placement with or without immediate loading is reported in daily dentistry and implantology, but these procedures are not common in the case of periradicular and periapical lesions around the tooth needed to be replaced. In the following retrospective evaluation, 10 cases with a 1-year follow-up were selected to propose the technique of an immediate provisional non-loading prosthesis being delivered on the same day of the post-extraction implant placement in multiradicular teeth affected by chronic periradicular and periapical lesions. Post-extractive sockets underwent immediate dental implant placement by filling the empty space with sterile, re-absorbable gelatin sponges. The widths of the alveolar ridge were measured on three-dimensional radiographs before and after the operation, 4 and 12 months later. Non-parametric statistics were performed to compare the outcomes over time with a level of significance of 0.05. Comparing the preoperative cross-sectional images of cone beam computerized tomography (CBCT) scans to the postoperative ones, it was noted that changes in the crestal ridge width, ΔCW, (compared to baseline) were negligible and not clinically appreciable. However, while ΔCW at 4 months appeared to be negative (-0.17 ± 045 mm), crestal width at 12 months was at the same level as the baseline (ΔCW = 0.02 ± 0.48 mm), with a significant difference between 4 and 12 months (p-value = 0.0494). Immediate implant placement with an immediate non-loading provisional customized healing abutment of polyether-ether-ketone placed into the post-extractive sockets with asymptomatic and large chronic periapical and periradicular lesions could represent a further treatment strategy for patients' rehabilitation and soft tissue preservation to replace a hopeless tooth.

Clinical and radiographic evaluation of peri-implant tissue changes associated with use of standard versus customized healing abutments

Clinical and radiographic evaluation of peri-implant tissue changes associated with use of standard versus customized healing abutments

Outcomes of bio-esthetic single implant-supported restorations after peri-implant soft tissue conditioning with two prosthetic techniques: A 1-year randomized clinical trial.

Providing a definitive restoration with an emergence profile matching that of the contralateral or extracted tooth should result in an esthetic peri-implant soft tissue contour. Whether a custom healing abutment improves the outcome of a bio-copied definitive restoration compared with a stock abutment is unclear. The purpose of this 1-year randomized clinical trial was to evaluate the peri-implant soft and hard tissues related to bio-esthetic single implant-supported restorations having a contralateral tooth-matching restorative emergence profile after peri-implant soft tissue conditioning with either custom or stock healing abutment for patients indicated for immediate implant placement. Twenty-four participants indicated for immediate implant placement in the maxillary esthetic zone received bio-esthetic single implant-supported restorations after peri-implant soft tissue conditioning with either a custom healing abutment (n=12) or a stock healing abutment (n=12). The pink and white esthetic score (PES-WES) was evaluated 6 and 12 months after implant placement. Peri-implant bone changes were measured with cone beam computed tomography (CBCT) scans at the same intervals. The PES-WES showed significant difference between the 2 groups at 6 and 12 months. The CBCT scans did not show significant difference between the 2 groups. The use of the bio-esthetic concept for immediate single implant placement achieved successful esthetic restorations after conditioning the peri-implant tissues using either custom or stock healing abutments. However, the use of custom healing abutments was associated with higher PES-WES values in comparison with the use of stock healing abutments.

Biomaterials and Clinical Applications of Customized Healing Abutment-A Narrative Review.

Customized healing abutments have been introduced in clinical practice along with implant surgery to preserve or create natural-appearing hard and soft tissue around the implant. This provides the benefits of reducing the overall treatment time by eliminating the second stage and reducing the elapsed time of the fabrication of the final prostheses. This article aims to review the types and properties of materials used for the fabrication of customized healing abutments and their clinical applications. Articles published in English on customized healing abutments were searched in Google Scholar, PubMed/MEDLINE, ScienceDirect, and the Scopus databases up to August 2022. The relevant articles were selected and included in this literature review. Customized healing abutments can be fabricated from materials available for dental implants, including PEEK, PMMA, zirconia, resin composite, and titanium. All the materials can be used following both immediate and delayed implant placement. Each material provides different mechanical and biological properties that influence the peri-implant tissues. In conclusion, the studies have demonstrated promising outcomes for all the materials. However, further investigation comparing the effects of each material on peri-implant soft and hard tissues is required.

Digital workflow for low-cost 3D printed custom healing abutment based on emergence profile CBCT segmentation

Several protocols have been used with computer-aided design and computer-aided manufacture (CAD-CAM) prostheses after image-guided implant surgery based on a prosthetically driven surgical plan. For delayed approaches, a CAD-CAM custom healing abutment can be manufactured before the surgery and installed immediately after implant placement. However, information on the use of emergence profile segmentation on which to base the digital design and on the use of low-cost 3-dimensional printers to produce custom healing abutments are lacking. The purpose of this article was to present a fully digital workflow to digitally design and 3-dimensionally print custom healing abutments with a biocompatible light-polymerizing resin based on the natural emergence profile of the tooth to be replaced.
