Predictors for long-term relapse of orthodontic treatment in patients with cleft lip and palate. A clinical follow-up study.

OBJECTIVES: To identify predictors for long-term relapse of orthodontic therapy in patients with cleft lip and palate (CLP). MATERIALS AND METHODS: Patients with uni- and bilateral non-syndromal CLP were followed up at least two years after completion of their orthodontic therapy. Plaster casts of the start of treatment (T1), after completion of treatment (T2), and at follow-up (T3) were measured using the modified Huddart Bodenham Index. Characteristics of multidisciplinary therapy were taken from the patient files. Potentially influencing factors of relapse were investigated using logistic regression analyses and Spearman correlations. RESULTS: In total 58.07% of the included 31 patients showed a stable treatment outcome at follow-up after an average of 6.9 years. Even if relapse occurred, 61.54% of these patients still showed improvement regarding their occlusion compared to baseline. Predictors for the occurrence of relapse were the severity of dysgnathia at baseline (p = 0.039) and the extent of therapeutic change (p = 0.041). The extent of therapeutic change was additionally a predictor for the extent of post-therapeutic relapse (ρ = 0.425; p = 0.019). CONCLUSIONS: Patients with CLP benefit from their orthodontic therapy in the long term despite an increased tendency to relapse. CLINICAL RELEVANCE: Results of this long-term study could be used to adapt the treatment concept for patients with CLP and reinforce the significance of a patient-centered orthodontic treatment concept for affected patients.

Do Adult Naïve Listeners Perceive Differences in Speech Before and After Therapy for Cleft Palate Speech Disorders? A Reliability Study of Perceptual Speech Ratings.

PURPOSE: This study compared the interrater reliability of adult naïve listeners' perceptual assessments of different speech variables in children with a cleft palate with or without a cleft lip (CP ± L). In addition, the study investigated whether the listeners were able to perceive differences in these speech variables before and after speech therapy for cleft palate speech disorders. METHOD: Thirty-four speech samples of 14 children with a CP ± L (14 samples collected immediately before 10 hr of speech intervention, 14 samples collected immediately after speech intervention, and six randomly selected samples that were duplicated to assess intrarater reliability) were perceptually assessed by 26 adult naïve listeners. The listening panel consisted of nine men and 17 women (age range: 18-51 years). The speech variables included speech understandability, speech acceptability, hypernasality, hyponasality, nasal airflow, and articulation, which were assessed on a visual analog scale. Furthermore, the need for speech therapy was assessed. RESULTS: Good to very good interrater reliability was observed for the naïve listeners' ratings of all speech variables. A significant time effect was found for the pre- and postevolution of the speech variables "speech understandability," "speech acceptability," "nasal airflow," and "articulation." This time effect indicates an improvement of these variables postintervention. According to the naïve listeners, children were less in need of additional speech therapy after the 10-hr intervention period compared to assessments before this intervention period. CONCLUSIONS: Adult naïve listeners perceptually identified an improvement in different speech variables after 10 hr of cleft palate speech therapy. These findings confirm previous assessments of expert speech-language pathologists and suggest that speech improvements after cleft palate speech therapy can also be perceived by communication partners outside the therapy room. Perceptual ratings of naïve listeners can, thus, be used to add life-situation significance to the assessments of experts. Future research could include both expert raters and caregivers or relatives of children with a CP ± L in listening panels, as previous knowledge on craniofacial anomalies may lead to different results.

Effects of nasoalveolar molding on maxillary arch dimensions and malocclusion characteristics in primary dentition patients with cleft lip and palate.

BACKGROUND: Nasoalveolar molding (NAM) is a presurgical orthopedic technique used in the management of cleft lip and palate deformities. Despite the widespread use of NAM therapy, there is a need for further investigation to assess its specific effects on arch dimensions and malocclusion characteristics. AIM: To evaluate the effects of NAM therapy on maxillary arch dimensions and malocclusion characteristics in patients with unilateral cleft lip and palate (UCLP) and bilateral cleft lip and palate (BCLP). DESIGN: Patients in primary dentition were referred to the Institutional Department of Orthodontics. The NAM group consisted of 21 patients with UCLP (mean age 4.7 ± 0.7 years) and 12 patients with BCLP (mean age 4.8 ± 0.7 years). Sixteen patients with UCLP (mean age 4.9 ± 0.9 years) and five patients with BCLP (mean age 5.4 ± 1.1 years) were included in the non-NAM group. The plaster models of all patients were digitized. Dental arch dimensions and malocclusion characteristics were analyzed via digital software. One-way ANOVA with Bonferroni correction was used for statistical analysis. RESULTS: Intercanine and intermolar widths showed statistically significant differences according to the cleft type (p < .01). There was no statistically significant effect of NAM therapy on maxillary arch parameters and malocclusion characteristics (p > .05). The prevalence of anterior crossbite was 12.1% in the NAM group and 23.8% in the non-NAM group. CONCLUSION: NAM therapy did not affect the maxillary arch dimensions and malocclusion characteristics in patients with UCLP and BCLP. The cleft type was the main factor, leading to a significant difference in maxillary widths.

Core outcomes for orofacial clefts: reconciling traditional and ICHOM minimum datasets.

OBJECTIVE/DESIGN/SETTING: This retrospective study sought voluntary participation from leading cleft centres from Europe and Brazil regarding core outcome measures. The results of this study would inform the debate on core outcome consensus pertaining to the European Reference Network for rare diseases (ERN CRANIO) and achieve a core outcome set for cleft care providers worldwide. INTERVENTION/METHOD: Five orofacial cleft (OFC) disciplines were identified, within which all of the International Consortium of Health Outcomes Measurement (ICHOM) outcomes fall. One questionnaire was designed for each discipline and comprised 1. the relevant ICHOM's outcomes within that discipline, and 2. a series of questions targeted to clinicians. What core outcomes are currently measured and when, did these align with the ICHOM minimum, if not how did they differ, and would they recommend modified or additional outcomes?. RESULTS: For some disciplines participants agreed with the ICHOM minimums but urged for earlier and more frequent intervention. Some clinicians felt that some of the ICHOM standards were compatible but that different ages were preferred and for others the ICHOM standards were acceptable but developmental stages should be preferred to absolute time points. CONCLUSION/IMPLICATIONS: Core outcomes for OFC were supported in principle but there are differences between the ICHOM recommendations and the 2002 WHO global consensus. The latter are established in many centres with historical archives of OFC outcome data, and it was concluded that with some modifications ICHOM could be moulded into useful core outcomes data for inter-centre comparisons worldwide.

Effects of Alt-RAMEC protocol with facemask therapy in cleft lip palate patients in a sample of Pakistani population.

OBJECTIVE: The objective of the study is to evaluate the skeletal, dentoalveolar and soft tissue changes before and after treatment with Alt-RAMEC protocol and protraction headgear in comparison to the controls. MATERIAL AND METHODS: A quasi experimental study was conducted in the orthodontic department on 60 patients of cleft lip and palate. These patients were divided into two groups. Group I was the Alt-RAMEC group that underwent Alt-RAMEC protocol followed by facemask therapy while group II was the control group that underwent RME and facemask therapy. Total treatment time in both the groups was approximately 6 to 7 months. Mean and standard deviation was calculated for all the quantitative variables. Pre and post treatment changes between treatment and control groups were made using paired t-test. Intergroup comparison between treatment and control group was analyzed using independent t-test. Significance for all tests was predetermined at a P-value of ≤ 0.05. RESULTS: The Alt-RAMEC group showed significant forward movement of maxilla and improvement in the maxillary base. A remarkable improvement in SNA was seen. The overall outcome was better maxillo-mandibular relationship as shown by positive ANB values and angle of convexity. More effect on maxilla and least effect on mandible was notified with Alt-RAMEC protocol and facemask therapy. Improvement in transverse relationship was also evident in the Alt-RAMEC group. CONCLUSION: Alt-RAMEC protocol in combination with protraction headgear is a better alternative to treat cleft lip and palate patients in comparison to the conventional protocol.

The restorative dentistry management of adult cleft patients: 'the adult returner'.

This paper will discuss the management of adult patients with cleft lip and palate who return to care, often many decades after their initial course of treatment. This can be a very complex group of patients to treat as they often present with anxiety about dental care and often have other long-standing psychosocial issues. Working very closely with the multi-disciplinary team and the general dental practitioner is crucial to the successful outcome of care. This paper will outline the most common complaints that these patients may present with and the restorative dentistry solutions that are available to address them.

The role of the clinical psychologist within a cleft service.

Clinical psychologists are core members of UK cleft services. This paper outlines the variety of ways in which clinical psychologists work across the lifespan to promote the psychological wellbeing of those born with a cleft and their families. In the context of dental or orthodontic treatment, this involves a combination of early intervention and advice, psychological assessment or specialist psychological therapy for individuals experiencing dental anxiety or anxiety regarding the appearance of their teeth. This paper therefore aims to highlight the varying roles which clinical psychologists play in the provision of cleft-related dental care, often alongside multidisciplinary colleagues.

Articulating the issues: speech assessment and intervention in cleft lip and palate.

This paper describes the impact of cleft lip and palate on speech. It provides an overview for the dental clinician of the key issues affecting speech development and clarity. The paper summarises the complex speech mechanism and cleft-related factors that affect speech, including palatal, dental and occlusal anomalies. It outlines the framework for speech assessment throughout the cleft pathway and provides a description of cleft speech disorder, as well as describing treatment approaches for cleft speech and velopharyngeal dysfunction.This is followed by a spotlight on speech prosthetics for treating nasal speech, with an emphasis on joint management by the Speech and Language Therapist and Consultant in Restorative Dentistry. This includes the core multidisciplinary approach, clinician and patient-reported outcome measures, and brief discussion of national developments in this area.The importance of multidisciplinary cleft care is highlighted and, within this, the essential interaction between speech and dental clinicians in providing routine care, as well as in delivering a highly specialist speech prosthetics service.

Global perspectives in orofacial cleft management and research.

Orofacial clefts (OFCs) refer to clefts of the lip and palate, a heterogeneous group of relatively common congenital conditions that can cause mortality and significant disability if untreated, and residual morbidity even when treated with multidisciplinary care. Contemporary challenges in the field include: lack of awareness of OFCs in remote, rural and impoverished populations; uncertainties due to lack of surveillance and data gathering infrastructure; inequitable access to care in some parts of the world; and lack of political will combined with lack of capacity to prioritise research.OFCs present clinically as either syndromic or non-syndromic, with the latter either being isolated or in conjunction with other malformations; however, many registries still do not differentiate between these fundamentally different entities and lump a spectrum of cleft types and sub-phenotypes together. This has implications for treatment, research and ultimately, quality improvement.This paper deals with the challenges in contemporary management in terms of care and the prospects and possibilities for primary prevention of non-syndromic clefts. In terms of management and optimal care, there are also challenges in the provision of multi-disciplinary treatment and management of the consequences of being born with OFCs, such as dental caries, malocclusion and psychosocial adjustment.

How acceptable is the use of linguistic-phonological intervention in children with cleft palate? A qualitative study in speech therapists.

BACKGROUND & AIMS: Even though evidence for the use of linguistic-phonological intervention approaches in children with a cleft (lip and) palate (CP±L) is still limited, these approaches are being used by speech-language pathologists (SLPs) to treat active or compensatory cleft speech disorders in clinical practice. It is, however, unknown to what extent linguistic-phonological intervention is acceptable to SLPs. The aim of this study is to investigate the retrospective acceptability of linguistic-phonological intervention in children with a CP±L from the perspective of SLPs using the theoretical framework of acceptability (TFA). METHODS & PROCEDURES: A total of 18 female community SLPs, aged between 23 and 63 years, were included in the study. An independent interviewer conducted semi-structured interviews. Data were analysed using a deductive coding approach. Statements of the SLPs were related to the seven constructs of the TFA: affective attitude, burden, ethicality, intervention coherence, opportunity costs, perceived effectiveness and self-efficacy. OUTCOMES & RESULTS: The affective attitude and perceived effectiveness of linguistic-phonological intervention differed among the SLPs: some therapists had positive attitudes towards these approaches, while others did not. Positive attitudes were related to the successful use of linguistic-phonological intervention in the past. The construct 'ethicality' revealed that negative attitudes towards these approaches were attributed to the limited available scientific evidence or negative experiences while using these approaches. In contrast, SLPs who had positive attitudes considered these interventions as 'important' and 'valuable'. Some SLPs had negative reflections on linguistic-phonological intervention as these approaches were considered demanding in terms of time needed to gain knowledge on using them in children with a CP±L (constructs 'burden' and 'opportunity costs'). Additionally, some SLPs doubted their self-efficacy to use these approaches in clinical practice. CONCLUSIONS & IMPLICATIONS: The acceptability of linguistic-phonological intervention differed between the SLPs in this sample and was most likely related to their previous experiences with these linguistic-phonological approaches. It is important to increase not only the amount of scientific evidence for linguistic-phonological approaches but also the supply of evidence-based workshops and training courses on this topic. These initiatives should distribute scientific information that is translated into guidelines that are immediately applicable in clinical practice. This may potentially reduce the time-related burden that some SLPs currently experience to gain expertise in this matter. In future research, it is necessary to investigate if there exist differences in acceptability between the different types of linguistic-phonological therapy. WHAT THIS PAPER ADDS: What is already known on this subject Linguistic-phonological speech intervention approaches are often used by SLPs to treat active or compensatory cleft speech disorders in clinical practice. What this paper adds to existing knowledge This study investigated whether linguistic-phonological intervention cleft speech intervention is acceptable to SLPs. Some therapists had positive attitudes towards these approaches, while others did not. Positive attitudes were related to the successful use of these approaches in the past. If SLPs indicated having negative attitudes, these negative feelings were attributed to the limited available scientific evidence or negative experiences while using these approaches. What are the potential or actual clinical implications of this work Even though linguistic-phonological speech intervention approaches are being used in clinical practice, these approaches are not always considered acceptable by SLPs. Acceptability could be enhanced by increasing the amount of scientific evidence for linguistic-phonological approaches, but also by increasing the supply of workshops and training courses on this topic. These initiatives should distribute hands-on information that is immediately applicable in clinical practice. This may potentially reduce the time-related burden that some SLPs currently experience to gain expertise in this matter.

Innovative Therapeutic Approaches for the Treatment of the Ocular Morbidities in Patients with EEC Syndrome.

Ectrodactyly-Ectodermal dysplasia-Clefting (EEC) syndrome is caused by heterozygous missense point mutations in the p63 gene, an important transcription factor during embryogenesis and for stem cell differentiation in stratified epithelia. Most of the cases are sporadic, related to de novo mutations arising during early-stage development. Familial cases show an autosomic dominant inheritance. The major cause of visual morbidity is limbal stem cell failure, which develops in the second to third decade of life. Patients often show ocular surface alterations, such as recurrent blepharitis and conjunctivitis, superficial microlesions of the cornea, and spontaneous corneal perforation and ulceration, leading to progressive corneal clouding and eventually visual loss. No definitive cures are currently available, and treatments to alleviate symptoms are only palliative. In this review, we will discuss the proposed therapeutic strategies that have been tested or are under development for the management of the ocular defects in patients affected by EEC syndrome: (i) gene therapy-based approaches by means of Allele-Specific (AS) siRNAs to correct the p63 mutations; (ii) cell therapy-based approaches to replenish the pool of limbal stem cells; and (iii) drug therapy to correct/bypass the genetic defect. However, as the number of patients with EEC syndrome is too limited, further studies are still necessary to prove the effectiveness (and safety) of these innovative therapeutic approaches to counteract the premature differentiation of limbal stem cells.

Interdisciplinary Team Care for Children with Facial Differences.

Children who have cleft and craniofacial diagnoses require coordinated, interdisciplinary treatment planning from birth to young adulthood. Teams that adhere to the Parameters of Care and maintain annual review by the American Cleft Palate Craniofacial Association Commission on Approval of Teams are published at www.acpa-cpf.org to assist families in obtaining that care. The six critical components to this interdisciplinary care focus on the team's composition, the team's management and responsibilities, the inclusion of patient and family/caregiver communication, an ongoing commitment to cultural competence, the importance of psychosocial and social services provided for the child and family, and the dedication to outcomes assessment. Primary care physicians are in a unique position to help direct families to this online directory for the best possible outcomes. [Pediatr Ann. 2023;52(1):e18-e22.].

A Systematic Review of the Cost-Effectiveness of Cleft Care in Low- and Middle-Income Countries: What is Needed?

OBJECTIVE: The objective of this paper is to conduct a systematic review that summarizes the cost-effectiveness of cleft lip and/or palate (CL/P) care in low- and middle-income countries (LMICs) based on existing literature. DESIGN: We searched eleven electronic databases for articles from January 1, 2000 to December 29, 2020. This study is registered in PROSPERO (CRD42020148402). Two reviewers independently conducted primary and secondary screening, and data extraction. SETTING: All CL/P cost-effectiveness analyses in LMIC settings. PATIENTS, PARTICIPANTS: In total, 2883 citations were screened. Eleven articles encompassing 1,001,675 patients from 86 LMICs were included. MAIN OUTCOME MEASURES: We used cost-effectiveness thresholds of 1% to 51% of a country's gross domestic product per capita (GDP/capita), a conservative threshold recommended for LMICs. Quality appraisal was conducted using the Joanna Briggs Institute (JBI) checklist. RESULTS: Primary CL/P repair was cost-effective at the threshold of 51% of a country's GDP/capita across all studies. However, only 1 study met at least 70% of the JBI criteria. There is a need for context-specific cost and health outcome data for primary CL/P repair, complications, and existing multidisciplinary management in LMICs. CONCLUSIONS: Existing economic evaluations suggest primary CL/P repair is cost-effective, however context-specific local data will make future cost-effectiveness analyses more relevant to local decision-makers and lead to better-informed resource allocation decisions in LMICs.

Three-dimensional Changes of Maxillary Alveolar Morphology After Using Modified Nasoalveolar Molding in Patients with Complete Unilateral Cleft lip and Palate.

OBJECTIVE: This study aimed to evaluate the three-dimensional changes in maxillary alveolar morphology after using modified NAM in patients with complete unilateral cleft lip and palate. DESIGN: This is a retrospective study. SETTING: The study was carried out in the dental hospital, Faculty of Dentistry of Naresuan University, Phitsanulok, which serves as a tertiary care center. PATIENTS: The population sample consisted of 19 patients with nonsyndromic complete unilateral cleft lip and palate. INTERVENTION: All patients received the modified NAM treatment based on the treatment protocol of the Naresuan University Cleft and Craniofacial Center, Thailand. MAIN OUTCOME MEASURE: Dental models obtained at pre-treatment (T0) and post-treatment (T1) were scanned to construct the digital models. The maxillary digital models that showed dimensional changes between T0 and T1 were measured using a computer graphic software. RESULTS: The modified NAM resulted in a significant decrease in the anterior cleft width, posterior cleft width, and anterior arch width. Conversely, it caused a significant increase in the length of the lesser cleft segment and the greater segment rotation. However, the change in the height of both segments and posterior arch width was not found to be significant. CONCLUSIONS: The modified NAM was an effective device for reducing the alveolar cleft width while improving the alignment of alveolar cleft segments.

Presurgical Orthopedic Treatment of a 3-Year-Old Child with Unoperated Complete Bilateral Cleft Lip and Palate and Protruding Premaxilla.

Unoperated patients with bilateral complete cleft lip and palate (BCCLP), who do not receive orthopedic treatment in infancy and present with significant sagittal excess of the premaxilla, are among the most difficult patients to treat. Delay in primary reconstruction reduces the elastic characteristics of the tissues. The resulting rigidity of bony structures accompanied by the wide alveolar and palatal clefts associated with sagittal excess of the premaxilla pose a great challenge for both surgeon and orthodontist. There is no unique protocol for treatment of these conditions. This paper describes the use of orthopedic treatment in an unoperated 3-year-old male child with BCCLP and a protrusive premaxilla whose appearance and function were both severely affected. A modified Meazzini technique, as described in operated BCCLP patients with a downward-displaced premaxilla, was used. The device itself consists of the 2 independent components mutually connected by a 17 × 25 steel arch. The first is an active fan-type expander. The second consists of an acrylic cap covering the premaxilla and 3 brackets used for the steel arch application. They are connected by a rectangular steel 17 × 25 archwire. Reduction of the premaxillary sagittal excess of is carried out with an elastic chain. The use of this orthopedic appliance is a reliable and valuable presurgical treatment in the therapy of children with BCCLP and protrusive premaxilla whose orthopedic and surgical treatment have been delayed.

Bite Force Changes in Bilateral Cleft Lip and Palate Patients Before and After ALT-RAMEC Protocol.

To evaluate the bite force (BF) changes in bilateral cleft lip and palate (BCLP) in contrast to the non BCLP children after ALT-RAMEC Facemask therapy.The prospective study was carried out on a total of 60 subjects of age 6 to 13 years in a tertiary care hospital; treatment group, 30 children with BCLP and control group, 30 children without cleft lip and palate. Each cleft patient was received ALT-RAMEC Facemask treatment and their BF assessed at 4 different stages. Bite force taken before treatment, immediately, 3 months and 6 months after treatment. Bite force of the control group was taken at baseline to compare with the treatment group to demonstrate the difference in BF values. Independent t test and analysis of variance were used to perform statistical analysis.There was a significant difference in BF between the treatment group (BCLP) 122.53 ± 8.64 N and the control group (non BCLP) 181.38 ± 18.84 N at baseline. After the Alt RAMEC protocol, changes in BF recorded over 3 and 6 months of therapy showed significant improvement. The mean values of BF at 3months and 6 months were 106.7 ± 9.3 N and 137.4 ± 9.5 N, respectively.Bite force was significantly improved after ALT-RAMEC protocol followed by facemask therapy in BCLP patients.

Craniofacial Orthodontic Experience in CODA-Accredited Orthodontic Residency Programs.

To evaluate orthodontic care for patients with craniofacial anomalies (CFA) by identifying orthodontic residents' preparedness to treat certain conditions and willingness to receive more training in CFA.A 12-question survey was sent through the American Association of Orthodontics (AAO) organization to orthodontic residents. Questions were primarily designed to obtain information on the frequency with which they dealt with patients with CFA in their training, specific craniofacial conditions that orthodontic residents feel comfortable treating.A total of 150 participants out of 1066 responded. Of the 150 responses, 35% were first-year residents, 43% second year, and 22% were third-year residents. Thirty nine percent of residents saw 3 or more CFA patients during their residency followed by 24% that saw no patients with CFA. Forty five percent reported that 1 to 3 hours of lecture time was devoted to CFA per month. Sixty percent felt their training in CFA was not sufficient to feel comfortable treating these patients in practice. Specifically, 62% felt comfortable treating Down syndrome, 84% unilateral cleft lip and/or palate, and 64% bilateral cleft lip and/or palate, while the majority did not feel comfortable treating Pierre Robin sequence (68%), Cleidocranial dysplasia (65%), Crouzon syndrome (75%), Pfeiffer syndrome (80%), Treacher Collins syndrome (76%), Apert syndrome (76%), CHARGE syndrome (84%), and DiGeorge sequence (84%). Seventy eight percent of residents reported that they would like more training in treating craniofacial.Orthodontic residents did not feel comfortable treating patients with CFA. Majority of the residents felt that they would like to learn more about CFA.

Global Trends in Knowledge, Attitude, and Awareness of Orthodontists Regarding the Management of Patients with Cleft lip and/or Palate: A Systematic Review.

The aim of the present systematic review was to assess the trends in knowledge, attitude, awareness, and practice among orthodontists regarding the management of patients with cleft lip and/or palate.An a priori protocol was developed as per the best practices of evidence-based medicine and registered in Prospero (CRD42022306107). The literature search was conducted electronically, using MeSH-terms, keywords, and Boolean-operators "AND" and "OR" in different combinations in multiple databases and screening of titles and abstracts followed by full-text evaluation was performed. The risk of bias (ROB) was assessed using Joanna Briggs Institute critical appraisal checklist.Five studies were included in the qualitative synthesis and three of them showed a high ROB. When participants were questioned about which other specialists worked in the cleft team in addition to the orthodontists, 84% of them in one study reported it to be general dentists. Furthermore, the absence of an interdisciplinary team was reported in two studies from Africa. When asked about the percentage of their practice devoted to the care of patients with cleft lip and palate (CLP) one study reported that 52% of orthodontists had treated <10 such patients in their entire career.The present systematic review highlights the lack of knowledge and experience among orthodontists and orthodontic residents regarding the management of patients with CLP. Efforts must be made to design validated questionnaires and conduct methodologically sound studies in different geographical locations to develop adequate modules for improving the knowledge of orthodontists in this domain.

Arch Symmetry in Patients Without and With Cleft Lip and Palate After Orthodontic/Rehabilitative Treatment-A Stereophotogrammetry Study.

To evaluate and compare the dental arch symmetry of individuals with and without cleft lip and palate after orthodontic/rehabilitation treatment.Cross-sectional study.Tertiary cleft center in Brazil.Fifty-five participants aged between 18 and 30 years were divided into 3 groups according to treatment. Patients that received either a fixed partial denture (FPD) or implant-supported crown (ISC) in the cleft area or only orthodontic treatment, noncleft patients (NC).An analysis was performed using digitized dental casts scanned by laser and software. The following linear measurements were evaluated: incisor-canine; canine-molar; incisor-molar; surface and volume of the palatal region.Three-way ANOVA was used to compare the study factors: group (FPD/ISC/NC) and side (right/left) followed by the Tukey test to verify their interaction (α = .05).The results showed statistically significant differences among groups for the maxillary linear measurements canine-molar and incisor-molar, but not for incisor-canine. No statistically significant differences were found regarding the side for the maxillary measurements, while the factor interaction showed similarity only for incisor-canine. The mandibular measurements showed no statistical differences among groups, sides, or factor interactions. In surface and volume, all values in patients with cleft presented lesser than in without cleft patients.Regardless of the rehabilitation, arch symmetry can be achieved in the incisor-canine dimension in the cleft area.
