“…12 Although the quality control is ensured during the manufacturing of the implants, the probability of metal leaching in surrounding tissues is not ruled out. 13 Chang et al reported approximately 5.3% incidence of the metallosis after total hip arthroplasty. 14 Ollivere et al reported a 3.1% incidence of metallosis after cognate prosthesis failure used in resurfacing of the hip.…”

Objective: The purpose of this longitudinal study was to surveil the serum titanium ion levels at various time intervals in patients with indigenous 3D-printed total temporomandibular joint replacement (TMJ TJR). Study design: The study was conducted on 11 patients (male: 8; female: 3) who had undergone unilateral or bilateral TMJ TJR. Blood samples were drawn preoperatively (T0), 3 months (T1), 6 months (T2), and 1 year (T3) postoperatively. Data were analyzed and a p value of <0.05 was considered statistically significant. Results: The mean serum titanium ion levels at T0, T1, T2, and T3 was 9.34 ± 8.70 microgram/L (mcg/L), 35.97 ± 20.27 mcg/L, 31.68 ± 17.03 mcg/L, and 47.91 ± 15.47 mcg/L respectively. The mean serum titanium ion levels increased significantly at T1 (p= 0.009), T2 (p= 0.032), and T3 (p=0.00) interval. There was no significant difference between unilateral and bilateral groups. Conclusion: Serum titanium ion continued to show increased levels till the last follow-up of 1 year. These initial serum titanium ion levels increase is due to the initial wear phase of the prosthesis which manifests over 1 year. Further studies with large sample sizes and long-term follow-ups are required to see the deleterious effect if any on the TMJ TJR.

“…This combination is the current standard for low-friction TMJ total joint arthroplasty. 41 Titanium and cobalt-chromium alloys are the only metals approved by the FDA for the fabrication of TMJR in humans. Relative to cobalt-chromium, Ti6Al4V offers the advantages to be less stiff and more conveniently machined.…”

OBJECTIVE To evaluate the kinematics and stability of the temporomandibular joint (TMJ) of cats and dogs with and without a TMJ replacement (TMJR) prosthesis under simulated bite forces and mouth opening. ANIMALS Sixteen cadaver skulls from domestic cats (n = 8) and medium- to large-breed dogs (n = 8). METHODS Intact TMJs were tested. Following condylectomy and coronoidectomy, the skulls were fitted with a TMJR prosthesis unilaterally and retested. Prosthesis was similarly implanted in the contralateral TMJ in 4 cats and 4 dogs before retesting. Left and right bite motions were evaluated before bite contact to peak bite force (200 N in dogs, 63 N in cats). Mouth opening motion was recorded. Mandibular displacement under load was evaluated in 3 orthogonal planes. Maximal displacement was compared between TMJR groups and native TMJ. Prosthesis-bone motion of the temporal and mandibular components was evaluated during simulated bites and mouth opening. RESULTS TMJR resulted in joint motion not demonstrably different from the native TMJ, with the ability to fully open and close the mouth and with minimal laterotrusion. The TMJR prosthesis demonstrated similar stability after unilateral and bilateral replacement during bite force and with an open mouth. Mean implant-bone motion during bite simulations for the temporal and mandibular TMJR components was ≤ 60 µm in cats and ≤ 30 µm in dogs. CLINICAL RELEVANCE A novel TMJR can be implanted and allows normal jaw motion. Joint stability is maintained after TMJR implantation in the TMJ of dogs and cats TMJ that is devoid of muscular support.
