Upon CBCT radiographic assessment, a radiopaque foreign body, identified as an antrolith, was discovered in the maxillary right sinus.
What is this foreign body? Hint: Patient had full mouth extractions with placement of an interim prosthesis.
A recent systemic review and meta-analysis study evaluated the implant failure rate of splinting vs. non-splinted implant prostheses.
Did splinted or non-splinted prosthesis have a greater implant failure rate?
According to a University Of Connecticut School Of Dental Medicine study, what percentage of patients seeking dental implant treatment were diagnosed with carotid calcifications as seen on CBCT examinations?

Answer: Tissue Conditioner: Following full-mouth extractions with the placement of an interim prosthesis, tissue conditioner was utilized for relining purposes. Due to an undiagnosed communication with the maxillary sinus post-extraction, the reline material, mixed with a low viscosity, extruded into the maxillary sinus. It’s worth noting that over 40% of maxillary molars have at least one root that extends into the maxillary sinus (i.e., commonly results in communication with the maxillary sinus after extractions).
PROSTHETIC QUESTION OF THE MONTH
Answer: Non-Splinted Implant Prosthesis was associated with a higher implant failure rate.

PATHOLOGY STUDY OF THE MONTH
Answer: After evaluating 1000 CBCT scans of patients seeking dental implant patients, 38% were diagnosed with carotid calcifications.
Note: Patients with Carotid Calcifications should be referred to their physicians for evaluation and treatment if indicated.
