Elcio Marcantonio-Junior
A case report is presented to describe the treatment of peri-implantitis around a single implant that had been in function for 10 years in the mandibular left molar region. A combination of decontamination procedures, a guided bone regeneration protocol, and connective tissue grafting successfully promoted bone formation around the implant.

Minimizing excess cement around implant restorations: an in vitro study of cementation techniques
Hayleen Moran
Nurit Bittner
The amount of excess cement that resulted from different cement application techniques was evaluated in terms of both the distance traveled below the finish line and weight. Based on the findings, the wall layer cementation technique, in which cement is brushed on the intaglio walls of the crown, is recommended to reduce excess cement around implant crowns.

An unusual clinical and histopathologic presentation of a maxillofacial ameloblastoma: a literature review and case report

Clayton Davis
Camila Pacheco-Pereira
This article describes a case of maxillofacial ameloblastoma and discusses the difficulty of using the most recent World Health Organization classification (2022) to differentiate clinically between primary sinonasal ameloblastoma and gnathic ameloblastoma with sinonasal extension. The authors suggest that variants with extensive involvement of the sinonasal region and maxilla be classified with a clinical diagnosis of maxillofacial ameloblastoma, regardless of the tumor origin.

Clear aligner therapy and symptoms of temporomandibular disorders: a case report

Dental providers must consider the potential contributory role of clear aligner therapy in temporomandibular disorders (TMDs) in patients who adapt poorly to occlusal changes. This case report presents the case of a 56-year-old woman who developed symptoms of TMD pain during aligner therapy. The patient was educated on TMDs, and the treatment protocol was adjusted to only nighttime aligner use, alleviating the patient’s TMD symptoms while she completed orthodontic treatment.

This study compared flexural strength, Weibull reliability, and internal fit among milled vs 3D-printed definitive and provisional materials. Milled specimens showed significantly higher flexural strength than 3D-printed specimens, while the marginal gap and internal fit of milled and 3D-printed crowns were comparable. All mean marginal gap values were within a clinically acceptable limit of less than 120 μm.

Mitra Ghazizadeh Ahsaie
Evaluation of the histopathologic diagnoses and radiographic characteristics of lesions associated with impacted teeth revealed that 64.6% of the lesions were dentigerous cysts (DCs) and 18.5% were odontogenic keratocysts. Lesions larger than 2.0 cm were 5.5 times more likely than smaller lesions to be diagnosed as non-DC lesions. Tumors were significantly more frequent in patients aged 18 years or younger, while cysts were more frequent in individuals older than 18 years.

Shear bond strength of resin cement to a CAD/CAM millable alloy subjected to various surface treatments

Maryam Firouzmandi
Melika Hadadi
This study assessed the effect of different surface treatments on the shear bond strength between a resin cement and a millable cobalt-chromium alloy. Surface roughening procedures—either sandblasting or acid etching of the alloy surface—significantly improved the shear bond strength of resin cement to milled alloy surfaces, while the use of metal primer between the alloy surface and resin cement did not.

Evaluation of single-step self-etching ceramic primer and zirconia primer for bonding to zirconia-reinforced lithium silicate ceramic

This study evaluated the influence of simplified ceramic surface treatments on the microshear bond strength of 2 resin cements, Monobond Etch & Prime (MEP) and Signum Zirconia Bond (SZB), to a zirconia-reinforced lithium silicate (ZLS) material. The results indicated that the ammonium polyfluoride–based MEP may be used as a substitute for surface treatment with hydrofluoric acid and silane, but the use of the zirconia primer SZB alone is not advised for bonding to a ZLS ceramic.
