A Custom Stabilizing Splint for the Management of BLCP with Protruding Premaxilla.

ABSTRACT: A severely protruding premaxilla in a patient with bilateral cleft lip and palate prevents functional closure of the orbicularis oris muscle and acceptable reconstruction of the nasolabial components during primary cheiloplasty. This is typically corrected with vomerine osteotomy and premaxillary setback, followed by cheiloplasty and rhinoplasty. Due to the risk of vascular compromise to the prolabium and premaxillary segment, the lip and nose repair is often staged after the vomerine osteotomy and premaxillary setback has healed. Stabilizing the premaxillary segment to allow adequate healing has been a topic of interest. Several methods have been described, but each is associated with varying degrees of compromise of the blood supply to the premaxilla. To combat this, the authors created a custom oral splint that effectively maintained the position of the premaxilla with minimal impingement of the blood supply. The authors present two cases in which a two-stage premaxillary setback with a custom-stabilizing oral splint was performed, followed by primary cheiloplasty and rhinoplasty in an age-appropriate and delayed presentation of bilateral cleft lip and palate and protruding premaxilla.

Project description:One therapeutical alternative in the treatment of functional disorders is the use of printed oral splints. The mechanical properties of these materials are highly essential to their clinical effectiveness, and their performance may vary depending on factors such as cleaning, post-polymerization, or their orientation during construction. The objective of this in vitro investigation is to evaluate the effectiveness of the selected materials in terms of their biaxial flexural strength in relation to the criteria listed above. Splint materials were used in the printing of 720 discs. The printing process was carried out in different orientations in relation to the building platform. Either an automatic or manual cleaning process was performed on the samples. For post-polymerization, either an LED or Xenon light was utilized. A piston-on-three-ball test was used to measure the biaxial flexural strength (BFS) of the materials after they were stored in water for either 24 h or 60 days. The homogeneity of the data was controlled by employing the Levene method, and the differences between the groups were analyzed using the ANOVA and Bonferroni methods. After being stored for twenty-four hours, the mean BFS ranged anywhere from 79 MPa to 157 MPa. Following a period of sixty hours, the BFS exhibited a substantial drop and revealed values that ranged from 72 to 127 MPa. There was no significant difference that could be identified between the materials or between the various cleaning processes. The results of post-polymerization showed that the LED light produced higher means than the Xenon light did. In terms of position, the mean values varied greatly, with 0°'s mean value being 101 MPa, 45°'s mean value being 102 MPa, and 90°'s mean value being 115 MPa. The use of a build orientation of 90° and post-polymerization with LED light resulted in significantly increased biaxial flexural strength. According to this study, this design should be implemented in order to ensure that splint materials have the highest possible strength.

Project description:IntroductionFoot pain can be a significant burden for patients. Custom foot orthoses (CFOs) have been a mainstay in podiatry treatment for foot pain management and improving foot function. However, little is known about podiatrists' experience of prescribing CFOs or patient experience of using foot orthoses (FOs), including CFOs, for foot pain.MethodsA focus group (FG) discussion with three FOs users (Female = 2 and Male = 1) was conducted in November 2022 within a private podiatry practice. This group represented non-experts from the general local population of individuals with existing or previous foot pain who have personally experienced using either over-the-counter FOs or CFOs. An online FG discussion with five musculoskeletal (MSK) specialist podiatrists (Female = 2 and Male = 3) was also conducted in December 2022. This group represented podiatrists with specialist knowledge in foot biomechanics and clinical experience in CFO provision. The FG discussions were recorded and lasted 49 and 57 min respectively. Transcribed data was manually coded, and a thematic analysis was undertaken to identify patterns within the collected data.ResultsThe participants in the patient FG detailed mixed experiences of the prescription process and CFOs received, with reports of limited involvement/input in their prescription, the need for frequent adjustments and high costs. The impact on footwear choices, replicability and transferability of CFOs into different types of shoes and technologies to aid design were also highlighted. In the podiatrist FG, lack of confidence in design and manufacture processes, prescription form language, relationship and communication building with manufacturers, variability in the CFOs issued and the need for better student education in CFO provision emerged as key themes.ConclusionPatients and podiatrists shared similar views on CFO provision, namely poor communication with manufacturers leading to dissatisfaction with the CFOs prescribed causing negative impacts on patient experiences. Podiatrists called for greater education at registration level to increase new graduate podiatrist knowledge in CFO design and manufacture and better collaboration with manufacturing companies.
