“…In this study, the horizontal widths from the implant surface to the mesial and distal socket wall were 1.59 mm and 1.89 mm. Even though some studies claimed that a large gap (4–5 mm) may heal spontaneously, without the application of regenerative materials [ 28 ]. Most authors recommended that augmentation procedures should be considered at the time of implant placement to reduce bone resorption [ 18 , 26 ].…”

Background To elucidate the anatomical features of the mandibular molar region to allow safe immediate implant placement. Methods Cone-beam computed tomography images of 150 patients (600 teeth) were reviewed retrospectively. The virtual implants were placed in the mandibular first and second molar region. The anatomic structures of the mandible and inter-radicular septum were both categorized into three types. The relationship between implant and inferior alveolar nerve (IAN), and the horizontal distance from the implant surface to the bone wall were analyzed. Variables were compared using a student’s t-test, or Mann–Whitney U test. Results Type U (39.0%) and type S (56.0%) were the most common in the first molar, while type U (67.7%) and type M (54.7%) had the highest prevalence rate in the second molar. The mean distance from the level where the virtual implant was completely surrounded by bone to IAN was 7.06 mm. The mean horizontal widths from the implant to the mesial and distal socket wall were 1.59 mm and 1.89 mm. The widths of the inter-radicular septum and the distances from implant to the buccal and lingual plate on different sections were significantly associated with tooth position (P < .05). Conclusions In the first molar region, the implant is suggested to be placed in the center of the inter-radicular septum, while in the second molar region, the mesial root socket could be considered. Immediate implant placement in the mandibular second molar sockets shows a high risk of IAN injury, lingual perforation, and inadequate primary stability.

“…They were usually allowed to fill with blood and any visible voids were blocked with hemostatic collagen sponge, only at the level of the healing abutment. Studies have pointed out that spontaneous bone formation will occur even in large defects, although most studies recommend the use of a grafting material when the jumping distance is more than 2 mm, Some have reported that even a jumping gap distance of 3 mm resulted in bone fill, although this may be related to the original thickness of the buccal socket wall …”

“…In the posterior jaw, however, immediate implant placement is far more challenging due to the complex anatomy . Various surgical approaches have been described to achieve the potential of immediate implant placement in molar sockets . Some authors have reported on placement of standard diameter implants into one of the molar sockets .…”

Background Although immediate implant placement for single rooted teeth is well documented, the prognosis of ultra‐wide implants in molar sockets lacks data. Purpose To evaluate the outcome of ultra‐wide implants, immediately placed in molar sockets. Materials and Methods Patients treated with immediate ultra‐wide diameter implants that have been in function for at least 40 months, were invited for a clinical evaluation. A radiograph was taken to measure marginal bone loss. Probing depths as well as plaque and bleeding scores were recorded at the implant and contralateral tooth. Crown and soft tissue dimensions were measured, and patients filled out an OHIP‐14 questionnaire. Results Eighty‐five out of 230 patients (37%) were evaluated. Twenty‐eight implants received a bone graft to fill the residual space. Average bone loss was 0.19 mm after a mean follow‐up of 67 months, with no significant changes over time (P = 0.170). There was no significant difference in bone loss between the maxilla and mandible (P = 0.797), male or female (P = 0.128), smoking and nonsmoking (P = 0.219), grafted and nongrafted sites (P = 0.098), or the different bio‐types (P = 0.404). The distal papillae were significantly higher if a contact point was present (P = 0.002). Plaque was more frequent at the contralateral tooth (P < 0.001), but more bleeding on probing was observed around the implants (P = 0.021). Overall, 63.5% of the patients experienced no problems at all. Conclusion Ultra‐wide diameter implants for immediate molar replacement demonstrate little bone loss and stable soft tissue conditions over a 4 to 7‐year period.
