Root Coverage Using a Novel Porcine Acellular Dermal Matrix: Case Reports of Different Minimally Invasive Techniques with a 3-Year Follow-up.

A recently released commercially available novel porcine acellular dermal matrix (PADM) appears to possess acceptable biologic and clinical properties to be considered as an acceptable soft tissue replacement material. The aim of these three case reports is to present the treatment of multiple gingival recession by means of different variations of the tunnel and PADM as well as the clinical outcomes obtained at 3 years postoperatively. The healing outcomes demonstrated only minor surgical complications, with minimal patient-reported discomfort.

Influence of the width of keratinized tissue on the development and resolution of experimental peri-implant mucositis lesions in humans.

Objectives: To analyze the influence of the width of keratinized mucosa (KM) on the development and resolution of experimental peri-implant mucositis lesions at abutments with different microstructures in humans.

Material And Methods: In a randomized, controlled study, a total of 28 patients had received 28 target implants exhibiting a KM ≥2 mm. These were randomly connected with either partially microgrooved- (test) (n = 15) or machined (control) (n = 13) healing abutments.

Onset, progression and resolution of experimental peri-implant mucositis at different abutment surfaces: A randomized controlled two-centre study.

Objectives: To assess the onset, progression and resolution of experimentally induced peri-implant mucositis lesions at abutments with different microstructures in humans.

Material & Methods: In a randomized, controlled, interventional two-centre study, a total of 28 patients had received 28 target implants and were randomly allocated to either partially microgrooved (test) or machined (control) healing abutments. The study was accomplished in three phases, including a wound healing period (WH) following implant placement (12 weeks), a plaque exposure phase (EP-21 days) and a resolution phase (RP-16 weeks).

Experimental peri-implant mucositis at different implant surfaces.

Objectives: To histologically and immunologically assess experimental peri-implant mucositis at surface enhanced modified (mod) hydrophilic titanium implants.

Materials And Methods: In a split-mouth design (n = 6 foxhounds), four different implants were inserted on each side of the maxilla: three titanium-zirconium alloy implants (TiZr) with either modSLA (sand-blasted, acid etched and chemically mod), modMA (machined, acid etched and chemically mod), or M (machined) surfaces in the transmucosal portion, and one titanium implant with a machined transmucosal portion (TiM). Experimental mucositis was induced at one randomly assigned side (NPC), whereas the contra-lateral maxillary side received mechanical plaque removal three times per week (PC).
