“…Similar high implant survival rates were also documented in other RCTs with the same study design as the present study, but a shorter follow-up. [5][6][7][8][10][11][12]17 Only 2 other published randomized studies reported results after a similar or longer follow-up period, that is 3 years 38 and 5 years. 39 The sample size of the present investigation, with 52 patients and 122 implants, is wider than other prospective studies, except for the study by Thoma and colleagues that was a multicenter study involving 4 centres.…”

“…3,4 Currently, there is no evidence of superiority of one technique over the other. High implant and prosthesis survival rates for both short implants (SIs) and standard length implants in association with sinus lift were reported in several medium-short term clinical studies [5][6][7][8][9][10][11] and systematic reviews. [12][13][14][15][16] In addition, no statistical differences were reported for marginal bone loss.…”

Background: Several treatment options exist for the implant-supported rehabilitation of edentulous posterior maxilla.Purpose: To compare maxillary sinus floor augmentation associated to standard length implants, with direct placement of implants of reduced length in the available residual bone. Materials and Methods:Patients with edentulous posterior maxilla and a residual height of 4-7 mm were randomly allocated to the test (short implants [SIs], 6.5 to 8.5mm long) or the control (sinus augmentation [SA] and implants 10mm long) group. Anorganic bovine bone was the grafting material for the control group. In both groups pure platelet-rich plasma was used to bioactivate implant surface prior to insertion. Implant and prosthesis survival, clinical variables, radiographic bone level change, quality of life, and patient satisfaction were assessed.Results: Twenty-five patients were treated in the control group (58 standard length implants) and 27 in the test group (42 SIs). After 3 years of follow-up no implant failure and biological or mechanical complications were recorded. Marginal bone loss, soft tissue, and oral hygiene parameters were similar in the 2 groups at both 1 and 3 years' follow-up. Postoperative pain, swelling and other symptoms and daily activities were better in the SIs group than in the SA group, while patients' satisfaction after 1 year was similar.Conclusions: In spite of comparable medium-term clinical and radiographic outcomes, when the residual ridge height is sufficient for a safe placement, SIs may be preferred due to simplified protocol, less invasiveness, shorter treatment time, and reduced postoperative discomfort as compared to SA.

“…This may be due to the fact that a block higher than 10 mm was placed, which resulted in a vertical increase higher than the indications suggested by previous studies. 5,16,17 This resulted in a decrease of blood supply to the grafted block, both directly from the underlying basal bone and indirectly from the coronally placed segment, which, in turn, was malperfused due to the extreme expansion, causing lingual periosteum tension.…”

This case report describes an inlay augmentation procedure with resorbable bone plates and fixation screws in a case of vertical atrophy of the anterior mandible. After 3 months from the surgery, vertical bone height augmentation was evaluated, and at the time of implant insertion, core biopsies from the grafted area were taken. Moreover, 8 months after the start of prosthetic loading, radiographic assessments showed no pathological signs. This case report shows that the effectiveness of resorbable plates during the graft healing process is similar to that of titanium plates.

“…In addition, they also reduce the morbidity, treatment time, costs and complications rates. 5,6,7,8,9,10 Initially, short implants had a standard diameter (3.75 mm), received no surface treatment, and present preponderant failures rates. 11,12,13 Recent studies have shown positive results for short implants 1,8,14,15,16 even for those shorter than 7 mm in length.…”

Short implants to support mandibular complete dentures - photoelastic analysis

This study evaluated the stress behavior around short implants in edentulous atrophic mandibles. Six groups included implants with two diameters regular and wide (4 and 5 mm) and three lengths (5, 7 and 9 mm) as follows: Ci9 (9 x 4 mm), Ci7 (7 x 4 mm), Ci5 (5 x 4 mm), Wi9 (9 x 5 mm), Wi7 (7 x 5 mm) and Wi5 (5 x 5 mm). These groups were compared to the control group CG (11 x 4 mm). The analysis was performed with the photoelastic method (n = 6). Each model comprised 4 implants with the same length and diameter connected by a chromium-cobalt bar that simulates a fixed denture. A 0.15 kg force was applied at the end of the cantilever (15 mm), and the maximum shear stress was recorded around the distal and subsequent implants. The stress values were determined, and the quantitative data (Fringes ® ) were submitted to statistical analysis with one-way ANOVA and the Dunnett test (p < 0.05). It was observed that the reduction in implant length increased stress values with a significant difference (p < 0.05) between CG Ci7 and Ci5, while the increase in implant diameter reduced the stress values without any differences found between short and long implants. Implants with 5 and 7 mm with regular diameter increased stress levels while short implants with larger diameters experienced similar stress to that of longer implants.

Vertical augmentation with interpositional blocks of anorganic bovine bone vs. 7‐mm‐long implants in posterior mandibles: 1‐year results of a randomized clinical trial

Abstract: When residual bone height over the mandibular canal is between 7 and 8 mm, 7 mm short implants might be a preferable choice than vertical augmentation, reducing the chair time, expenses and morbidity. These 1-year preliminary results need to be confirmed by follow-up of at least 5 years.
