“…With respect to the two poor PES‐scores; in one case, the soft tissues were damaged during implant installation, in the other the tip of the implant was too much tilted towards the buccal crest, thereby creating a gap lesser than 2 mm. The high total WES and PES scores at T3 are in confirmation with earlier reported results, in which on average a total WES score of 8.4 and a total PES‐score of 11.8 was achieved after 103 weeks. Also the prospective study of Cosyn et al reported a high mean PES of 12.15 1 year after IIPP ( n = 20).…”

“…To achieve optimal ridge preservation simultaneously with implant placement, research corroborated that a minimum thickness of at least 2 mm buccal hard tissue should be present . Retrospective results of our IIPP procedure revealed that, in case of application of a bovine substitute, the buccal crest thickness increased from 0.9 to 2.4 mm . After 2 years, this buccal crest thickness compacted to 1.8 mm.…”

“…The surgical and restorative procedure was performed following a standardized protocol. 31 To summarize; in cases of a failing maxillary incisor, an implant was placed immediately following atraumatic tooth extraction. As no flap was raised, the keratinized gingiva remained untouched.…”

“…29,30 Retrospective results of our IIPP procedure revealed that, in case of application of a bovine substitute, the buccal crest thickness increased from 0.9 to 2.4 mm. 31 After 2 years, this buccal crest thickness compacted to 1.8 mm. In the same period, the mean height of the buccal crest increased by 1.6 mm, which was in confirmation with the results found in ridge preservation studies using bovine bone substitute.…”

Background Prospective aesthetic outcomes on a high number of patients after immediate implant placement and provisionalization (IIPP) are lacking. Purpose To analyze the aesthetic outcome after IIPP. Materials and Methods One hundred consecutive patients with a failing maxillary incisor were provided with an immediately placed and provisionalized nonloaded implant using a flapless procedure and palatal implant positioning. The remaining gap buccally was filled with a bone substitute. Preoperatively (T0), 2 weeks postoperatively (T1), direct after placement of the permanent crown (T2), and 1 year after IIPP (T3), standardized light photographs were made. Change in aesthetic score was the primary outcome measure. Both the white aesthetic score (WES) and pink aesthetic score (PES) were used. Results In the first year postsurgery, the mean total‐WES and total‐PES scores raised from 4.5 to 8.2, and from 9.9 to 12.1, respectively. The mean PES scores for mesial and distal papilla, soft tissue marginal level, contour, color, and texture, raised significantly (P < .05), while the alveolar process contour, on average, remained stable from T0 to T3. Conclusions Within the limitations of this 1‐year research, it may be concluded that, following this minimal invasive IIPP procedure, a high aesthetic outcome was achieved.

“…Benic and colleagues followed 14 patients over 7 years and found a median buccal bone thickness of 0.0 mm (mean 0.4 mm). Groenendijk and colleagues reported in a 2‐year retrospective study on 16 patients a buccal bone thickness of 1.8 mm (varying from 0.9 to 2.4 mm). Raes and colleagues reported on a 8‐year prospective study with 16 patients with immediate placement.…”

Background There is lack of studies regarding preservation and possible changes in BBT at dental implants. Purpose To assess, on cone beam computer tomograms, the presence of bone at the time of tooth extraction in the maxillary esthetic region and the mean buccal bone thickness 1 month and 1 year after final restoration placement in patients with large bony defects. Material and Methods In a cohort study, patients were selected presenting a failing tooth with a large bony defect (test group [ n = 20]: large bony defect , immediate placed implant and delayed provisionalization). Results were compared with a group in which patients presented a failing tooth without or with a small bony defect: (control group [ n = 20]: without or small bony defect , immediate placed implant and delayed provisionalization). Cone beam computer tomograms were made preoperatively, and 1 month and 1 year after placement of the restoration, and buccal bone thickness was analyzed. Results In both groups approximately 1 mm of buccal bone thickness was present after 1 month and 1 year, without a significant difference between the groups. Conclusion In patients with large bony defects at a failing tooth it was possible to create a bone layer buccally of the implant and this bone layer remained stable during a 1‐year follow‐up; there were no significant differences between thickness of buccal bone at 1 month and 1 year in patients with large buccal bony defects and patients without or with small bony defects.
