“…The width‐to‐height ratio of peri‐implant mucosa appears inverted to what was measured on free gingiva around teeth, where the height was found to surpass width by a ratio of 1.5 (Wenstrom et al 1996) albeit the anatomic location of the measurements in teeth and implants might not be directly comparable. The lack of keratinized mucosa is another morphological feature of the peri‐implant mucosa that has been associated with an increased risk for mucositis (Mancini et al 2024 ) and peri‐implantitis (Mahardawi et al 2023 ).…”

ObjectivesThe primary aim of this cross‐sectional study was to investigate the association between prosthesis design and peri‐implant mucosa dimensions and morphology. The secondary aim was to investigate associations between mucosal dimensions and the presence of mucositis.Materials and MethodsForty‐seven patients with 103 posterior bone level implants underwent clinical and radiographic examination, including cone beam computer tomography and intraoral optical scanning. Three‐dimensional models for each implant and peri‐implant mucosa were constructed. Vertical mucosa height (TH), horizontal mucosa width at implant platform (TW), and 1.5 mm coronal of the platform (TW1.5), as well as mucosal emergence angle (MEA), deep angle (DA), and total contour angle (TA) were measured at six sites for each implant.ResultsThere was a consistent correlation between peri‐implant mucosa width and height (β = 0.217, p < 0.001), with the width consistently surpassing height by a factor of 1.4–2.1. All three angles (MEA, DA, TA) were negatively associated with mucosa height (p < 0.001), while DA was negatively associated with mucosa width (TW1.5) (p < 0.001, β = −0.02, 95% CI: −0.03, −0.01). There was a significant negative association between bleeding on probing (BoP) and mucosa width at platform (OR 0.903, 95% CI: 0.818–0.997, p = 0.043) and 1.5 coronal (OR 0.877, 95% CI: 0.778–0.989, p = 0.033). Implants with less than half sites positive for BoP (0–2/6) had significantly higher mucosa height (OR 3.51, 95% CI: 1.72–7.14, p = 0.001).ConclusionsProsthesis design can influence the dimensions of the peri‐implant mucosa, with wider emergence profile angles associated with reduced peri‐implant mucosa height. In particular, a wider deep angle is associated with reduced mucosa width in posterior sites. Reduced peri‐implant mucosa height and width are associated with more signs of inflammation.Trial RegistrationRegistered in Thai Clinical Trials Registry: http://www.thaiclinicaltrials.org/show/TCTR20220204002.

ObjectiveTo assess the clinical outcomes by means of implant and prosthetic survival of late placed and early loaded implants with a hydrophilic, moderately rough surface for partially edentulous patients after a follow‐up of 8.5 to 9.5 years.Materials and methodsA prospective case series study involving 15 patients with single, late placed and early loaded implants in the posterior mandible was performed. Clinical and radiographical parameters, including biological and technical complications and patient satisfaction, were assessed.ResultsFrom an initial sample of 15 patients, 12 were included. A total of 16 implants were observed. After a mean follow‐up of 9 years and 7 months (SD ± 3.8 months), implant success and survival rate were 100%. The prosthetic survival rate was 100%, and the prosthetic success rate was 93.8% since a major chipping was observed. No biological complications were observed, and the mean modified plaque index was 0.03 (SD ± 0.09) with a mean probing pocket depth of 2.95 mm (SD ± 0.09). A mean marginal bone level (MBL) of 0.04 mm (SD ± 0.88) and a mean VAS of 9.42 (SD ± 0.90) for patient satisfaction were recorded.ConclusionLate placed and early loaded implants with a moderately rough endosseal surface are a reliable option for rehabilitating partially edentulous patients. An implant survival rate of 100% and a prosthodontic success rate of 93.8% were observed. Patient satisfaction scores were high and peri‐implant hard and soft tissues remained healthy. The study findings should be carefully interpreted because of the small sample.

PurposeTo investigate the effect of mid‐buccal peri‐implant keratinized mucosa width (KMW) ≥2 mm or peri‐implant KMW >0 mm and <2 mm on the long‐term outcomes of peri‐implantitis reconstructive treatment.Materials and MethodsTwenty‐nine patients (40 implants; mean follow‐up: 9.2 ± 1.4 years) with at least one implant affected by peri‐implantitis and surgically treated through a reconstructive procedure followed by a submerged healing were included. Patients were categorized according to their initial KMW: Group 1 (KMW ≥2 mm) and Group 2 (KMW >0 mm and <2 mm). Peri‐implant clinical and radiographic parameters and a dedicated composite outcome were assessed at different follow‐up visits during supportive peri‐implant therapy for up to 10 years. Regression analyses were utilized to identify possible risk/predictive indicators for probing pocket depth (PPD) change and treatment success at the latest follow‐up.ResultsThe mean PPD did not exhibit any statistical difference from the baseline to the latest follow‐up between the groups at both patient and implant levels. Long‐term treatment success was 46.6% (Group 1) and 42.6% (Group 2) at patient level, it was 42.8% (Group 1) and 33.3% (Group 2), respectively, at implant level (p > 0.05). Group 1 demonstrated significantly higher vertical defect depth reduction than Group 2 (p = 0.018). Presence of buccal bony wall and mean PPD at the baseline were found to be associated with mean PPD change, while KMW at 6 months following surgery was identified as the only significant indicator for treatment success (p < 0.05).ConclusionImplants with KMW ≥2 mm did not present significantly better long‐term clinical outcomes following reconstructive therapy than those exhibiting KMW >0 mm and <2 mm. However, KMW values at the end of healing phase following a submerged approach had a significant impact on long‐term treatment success.
