“…No significant differences between the groups were found for any of the parameters analyzed ( p > .05). The results of the present study are in line with previously published data, demonstrating changes of the soft tissue contour along with changes of the hard tissues following tooth extraction (Araujo & Lindhe, ; Araújo, Silva, Mendonça, & Lindhe, ; Barone et al, ; Clozza et al, ; Jung et al, ; Sbordone et al, ; Schneider et al, ). However, methodological differences hamper a direct comparison of the studies.…”

“…Using a different primary outcome (expressed in mm 3 ) and two bone substitutes with porcine origin, Barone et al () found a mean loss of 244 mm 3 (pre‐hydrated collagenated cortico‐cancellous porcine bone group) and 349 mm 3 (cortical porcine bone group) after only 3 months. Another RCT with a negative control group and a DBBM test group (Sbordone et al, ) presented similar findings when compared to a previous study (Barone et al, ), always demonstrating an overall reduction from the original volume (expressed in mm 3 ), with a reduction of 400 mm 3 at control group and 210 mm 3 at DBBM group after 5 months. A recent RCT evaluating soft tissue changes in posterior sites after 6 months (Tomasi et al, ) found interesting results, where the DBBM‐C showed a soft tissue remodeling of 21.3%, a similar amount in the negative control group (20%).…”

Objectives To test the non‐inferiority of demineralized bovine bone mineral (DBBM) compared to demineralized bovine bone mineral with 10% collagen (DBBM‐C) for the maintenance of the soft tissue contour after tooth extraction in the esthetic zone. Material and Methods Sixty‐five patients randomly received ridge preservation at a single site in the anterior maxilla with DBBM or DBBM‐C. Both, DBBM and DBBM‐C, were covered with a collagen matrix. Profilometric analyses were performed at baseline (BL), immediately after treatment (PO), and at 4 months (FU; day of implant placement). The main outcome was the horizontal mean change (HC) at the buccal aspect. The measurements also included changes of the estimated soft tissue thickness (eTT) at 1, 3, and 5 mm below the buccal gingival margin. Descriptive analysis was performed, and differences between groups were analyzed using independent samples t test. The non‐inferiority test was performed for HC. Results At 4 months, the horizontal mean change (HC) was −1.43 mm (±0.53 mm) (DBBM‐C) and −1.32 mm (±0.53 mm) (DBBM). Change of the estimated soft tissue thickness (eTT) between baseline (BL) and four months of follow‐up (FU) at 1, 3, and 5 mm amounted to −4.58 mm (±2.02 mm), −2.40 mm (±0.97 mm), and −1.37 mm (±0.78 mm) for DBBM‐C and to −4.12 mm (±1.80 mm), −2.09 mm (±0.91 mm), and −1.23 mm (±0.72 mm) for DBBM. The differences between the groups were not statistically significantly for any of the outcome measures (p > .05). Conclusions DBBM is non‐inferior to DBBM‐C for the maintenance of the soft tissue contour 4 months after tooth extraction.

“…A negative value representing a bone loss. Implant survival: an implant was considered to have survived as already described in previous. papers and in addition when functionally loaded and lost at the removing time. Implant crown survival: an implant crown was considered to have survived unless fractured in the restorative material or upon fracture or loosening of the abutment/retaining screw or not in place because of implant loss or implant fracture.…”

Background A 5‐year longitudinal cohort study was carried out to evaluate the influence of anatomical crown to implant ratio (CIR) on peri‐implant marginal bone level (MBL) in single implants. Materials and Methods The longest possible implants, according to the availability of pristine bone, were inserted, one per patient, among periodontally healthy teeth in consecutively recruited subjects. CIR and MBL changes were measured on standardized radiographs. The relationship between MBL and multiple predictors was investigated. A statistical analysis suitable for mixed type distributions was conducted: for the discrete component a logistic regression model was used and for the continuous component the impact of the variables on MBL was examined by using robust nonparametric comparison tests. Results Seventy‐eight dental implants were inserted in 34 mandibles and 44 maxillae, with one stage procedure in 40 cases and two stage in 38 cases. Thirty‐five implants were <10 mm, while 43 were ≥ 10 mm long; 28 implants had a CIR ≤1 and 50 had a CIR >1. No drop‐outs or implant loss were observed. Bone loss occurred only in a few cases, measuring less than 0.5 mm and being significantly more pronounced for implant length ≥10 mm, for lower CIR values and for the two stage procedure. Conclusion Higher CIR values were not related to increased peri‐implant bone loss; a <10 mm long implant insertion may be safely considered for reduced bone heights.

“…When ridge preservation therapies were performed at extraction sites, they resulted in a statistically significant reduction of postextraction dimensional changes . A 1.83 mm decrease in resorption of the alveolar ridge width and 1.47 mm decrease in vertical height loss was found in one study …”

“…Ridge preservation procedures have been developed with the aim of reducing the dimensional changes of alveolar bone after tooth extraction; this, in turn, will facilitate subsequent prosthetic treatment using dental implants by allowing a more optimal implant placement in accordance with the occlusal scheme . Both preclinical and clinical studies have investigated the changes which occur after tooth extraction when the site is left to heal on its own and when ridge preservation procedures have been performed …”

Background The effect of different surgical techniques for ridge preservation on soft tissue parameters has seldom been investigated. The objective of this study was to compare the effect of two different ridge preservation techniques on soft and hard tissue dimensions. Methods Thirty patients requiring tooth extraction were randomly allocated to either control group C (allograft covered with a non‐crosslinked collagen membrane with primary closure) or experimental group E (allograft covered with cross‐linked collagen membrane left exposed). Sites were surgically re‐entered at 6 months. Soft and hard tissue measurements, cone beam computed tomography (CBCT), and cast measurements were taken at baseline and 6 months. Results Twenty‐eight patients were included in this analysis. When the two treatment groups were compared, the width of the buccal keratinized tissue in the E group showed an increase of 0.43 ± 0.42 mm compared to net loss of 1.57 ± 0.51 mm for the C (P = 0.006). Similarly, buccal tissue thickness has increased in the E group 0.46 ± 0.22 mm compared to a loss of 0.15 ± 0.23 mm in the C group (P = 0.068). Volumetric assessment of the changes in the alveolar ridge for the E group showed a slight decrease (68.3 ± 17 mm3) whereas the C group has experienced almost double this loss (107.5 ± 11 mm3; P = 0.07). Crestal width, measured on the CBCT scan, has shown significant reduction in the C group (4.18 ± 0.56 mm) compared to only 1.74 ± 0.4 mm in the E group (P = 0.003). Conclusion Crosslinked collagen membrane with allograft placed intentionally non‐submerged resulted in better preservation of the keratinized tissues (width and thickness) with similar and at times better osseous preservation following extraction.

Evaluation of volumetric dimensional changes in posterior extraction sites with and without ARP using a novel imaging device

Abstract: The dimensional loss in postextraction sockets grafted with anorganic bovine bone substitute and covered by a resorbable collagen barrier was lower than that of the naturally healing sites. However, ridge preservation was able to maintain almost 80% of the pristine bone.
